Create a single self-contained SVG illustration of the Sony PS5 Pro DualSense wireless controller at MAXIMUM fidelity. This is a showcase piece: take your time to plan the geometry carefully before writing it. Requirements: 1) Accurate DualSense silhouette and proportions: a wide body with the large, wide touchpad spanning the top centre, two flared, rounded grips sweeping down and outward, and a perfectly symmetrical left/right layout. White outer shell with the black central core section. 2) Face buttons on the right in the classic diamond: triangle (top), circle (right), cross (bottom), square (left), each drawn as clean PlayStation symbols in their real colours (green triangle, red circle, blue cross, pink square) in the modern outline style on light buttons, with subtle bevels. 3) D-pad on the left as FOUR separate arrow-shaped directional buttons (up, down, left, right), not a single cross. 4) Two black analog sticks with concave tops and a textured grip ring (fine radial or dotted texture) and shading. 5) The PlayStation logo button centred below the touchpad between the sticks, the small mic mute button with its orange-tinted indicator line just below it, the Create button (left) and Options button (right) flanking the touchpad. 6) The blue light-bar glow running along both side edges of the touchpad, with a soft bloom. Speaker grille holes on the black core. 7) Realistic product-render shading: gradients, specular highlights, soft ambient occlusion, a contact shadow beneath the controller. 8) A clean dark studio background with a subtle radial vignette. Front-on hero shot, centred and filling the frame well. Use viewBox="0 0 1600 1100" with width="1600" height="1100". No external assets, no raster images, no fonts, no scripts. Output ONLY the complete SVG code, starting with <svg and ending with </svg>, with no explanation or markdown fences. Save it as controller.svg in the current directory. You may render and inspect your own output (headless chromium is available at /usr/bin/chromium) and iterate on your own before finishing.

Build a playable, cinematic single-page Three.js experience: a small boat drifting through a Norwegian-style fjord / coastal mountain landscape.

Requirements:
- ONE self-contained index.html file (HTML + CSS + JS inline). No external assets of any kind (no textures, models, fonts, audio files) EXCEPT Three.js itself, loaded via an import map from this exact pinned CDN:
  "three": "https://cdn.jsdelivr.net/npm/three@0.160.0/build/three.module.js",
  "three/addons/": "https://cdn.jsdelivr.net/npm/three@0.160.0/examples/jsm/"
  All textures (water normals, rock, snow, bark, clouds, etc.) must be generated procedurally in code (canvas / DataTexture / shaders).
- Scene content: steep procedural fjord walls and mountains with snow caps, rock and grass coloring by height/slope; procedural conifer forests (instanced); a water surface with animated waves and sky/landscape reflections; a lighthouse on a rocky point with a rotating beam that matters at night; a small wooden boat with 2 simple stylized 3D characters on it (one rowing/steering, one looking around, with small idle animations); distant islands; birds or other small life if cheap.
- Dynamic weather cycling clear -> fog -> rain -> storm -> clearing, with smooth transitions: fog density, cloud cover, rain particles, lightning flashes + wind and bigger waves in the storm.
- A full day/night cycle: sunrise, day, golden hour, sunset, night with stars and moon, lit lighthouse and boat lantern. Sky color, sun/moon lights, and fog color must track time of day.
- Controls: keyboard (WASD/arrows to steer and throttle the boat, C to switch camera, T toggles auto-tour, 1-5 to force weather, N to jump time) and touch (on-screen joystick/buttons on phones). Camera follows the boat in play mode.
- An "auto-tour" cinematic camera mode: slow, smooth, film-like camera moves (orbits, low water-level glides, high establishing shots, close-ups of the characters) while the boat drifts along a path through the fjord and the weather and time of day progress.
- Minimal, elegant UI: small title "Fjordlys" (or a better name of your choice), a tiny hint line for controls, fading out in tour mode.
- Must run smoothly on desktop and phone browsers: keep geometry/particle counts moderate, cap devicePixelRatio at 2, handle resize/orientation.
- IMPORTANT for automated video capture, support these URL parameters:
  ?tour=1        start directly in auto-tour mode
  ?capture=1     hide ALL UI overlays (title, hints, touch controls)
  ?cycle=40      when present, compress one complete showcase into that many seconds: the time of day goes from morning through golden hour, sunset and night, and the weather passes clear -> fog -> rain -> storm -> clearing within that span (so a 40-second recording shows everything). Without it, use a relaxed pace suited to live play.
  Drive all animation from the requestAnimationFrame timestamp / performance.now() (not from wall-clock-independent accumulators that ignore time), so that overriding those functions steps the scene deterministically. Set window.__sceneReady = true once the first frame has rendered.
- No console errors or warnings in a current Chrome. Use modern Three.js r160 APIs only (no deprecated/removed ones).

ok here it is - my first Opus 5.5 vibecoded threejs 3D experience

my God!! Opus is creative!!

I made a road that forgets which way is down.

It folds 90° up a yellow wall, runs upside down across a ceiling, and turns into sheet music: steer through the notes to play each street's melody.

Watercolour. Ink. A radio on the roof.

Build a small playable 3D game in Three.js: an ant defends its home from a furious giant gardener. The player controls the ant on the ground of a lush garden, seen from a low third-person camera that makes the grass blades, pebbles and flowers feel huge. The gardener towers over the scene and sweeps a humming string trimmer back and forth, chasing the ant and throwing up clippings. The ant fights back with a tiny slingshot: aim with the mouse, fire pebbles at the gardener and dodge the trimmer's swings. Show a health bar for the ant and a large health bar for the gardener at the top of the screen, with hit flashes, a clear win or lose message and a restart. Warm afternoon sunlight falls through the leaves overhead, casting moving dappled light and soft shadows, with dust drifting in the light beams. Keep the controls simple (WASD or arrow keys to move, click to shoot) and show them on screen. Everything is built in code from Three.js geometry and materials; no external models or textures.

# Test: threejs_artwork_style_pass

Build a real-time 3D scene in three.js: a **caped flying hero** flies through a row of **large framed artworks**, and each time he passes through a frame **his rendering style changes to match that artwork's style**.

- The hero is an original, generic caped flyer (your own design, not any existing or trademarked character): a stylised humanoid in a flying pose, fists forward, with a cape that flutters and ripples in the wind as he flies.
- A row of at least **five big picture frames** stands along his flight path, spaced out, each with a gilded frame and a procedurally generated canvas in a different style, for example: **oil painting** (thick brush strokes), **ukiyo-e woodblock** (flat colours, bold outlines, wave pattern), **pixel art**, **comic book / halftone** (dots, ink outlines), **watercolour** (soft bleeding washes). More styles are welcome.
- As he flies **through** each frame, the hero's look switches to that artwork's style (custom shaders / materials / post-processing, e.g. toon shading + outlines, halftone dots, pixelation, painterly noise, paper texture), ideally with a short visible transition at the moment he crosses the frame plane. Optionally the world around him can also take on the style.
- Motion must be **smooth and continuous** (no teleporting or snapping): he flies along a gentle curved path through all frames, and the whole sequence loops seamlessly.
- The **camera follows** him smoothly (chase camera with slight lag), keeping both the hero and the next frame in view.
- Good lighting, sky/background and atmosphere; aim for a polished, showcase-quality look.

Build a Three.js scene: A retro arcade claw machine with a glass cabinet, chasing marquee lights and a pile of round pastel plush creatures stands in a dim arcade. Use the arrow keys to move the three-pronged claw over the pile and Space to drop it; the claw descends, closes, and may grip a plush that sometimes slips during the lift. A successful grab drops the plush down the prize chute with a burst of confetti; the camera is front-facing with slight mouse parallax. Everything is built in code from Three.js geometry, materials and shaders; no external models, textures or fonts. The scene must visibly animate from the moment it loads and run in a browser with software WebGL (no GPU).

Build a Three.js scene of a huge glowing jellyfish walking through a rainy city at night on very tall, thin, jointed legs, presented as a live disaster news broadcast. The jellyfish's translucent bell pulses with soft bioluminescent light, its tentacles sway beneath it, and each slow stride steps between the towers while rain streaks through the light and wet streets reflect neon signs and headlights. Frame it like a TV emergency broadcast: a main camera feed plus several smaller feeds from other angles (street level, a helicopter, a rooftop) that update as the creature moves; a HUD with a channel logo, a red LIVE badge, a scrolling news ticker, a clock and coordinates; and an event log panel that adds timestamped entries as the jellyfish crosses the city. Keep the mood tense and cinematic, with fog, flickering streetlights and flashing red and blue emergency lights. Everything is built in code from Three.js geometry, shaders and materials; no external models or textures. Build it as index.html (plus any local asset files you create) in the current directory.

# Test: threejs_mechanical_bee

Build a real-time 3D scene in three.js of an animated **mechanical (clockwork) bee**.

- The bee is built from many distinct parts: a segmented abdomen, thorax, head with compound-eye lenses, antennae, six jointed legs and two pairs of wings.
- Materials are physically based (MeshStandardMaterial or MeshPhysicalMaterial): polished and aged **brass**, brushed **steel**, a little dark enamel or glass, with believable metalness/roughness. Use an environment map (e.g. RoomEnvironment with PMREMGenerator) so the metal reflects.
- The **wings beat fast** (a visible blur-like flutter, thin translucent panels with a metal frame/veins).
- Several visible **gears turn** inside the body (meshing gears turn in opposite directions at speeds consistent with their tooth counts).
- The whole bee **hovers with a gentle bob and slight sway loop** in mid-air; legs and antennae move a little.
- **OrbitControls** let the viewer orbit, zoom and pan around the bee, with damping.
- **Nice lighting**: a key light with soft shadows, a fill and a rim light, tone mapping (ACES or AgX) and sRGB output; a tasteful backdrop or ground so the shadow reads.
- Aim for a polished, showcase-quality look.

Build an interactive Three.js scene of a single red Japanese maple (momiji) standing on a small rocky island in a still, misty lake. Its leaves are deep autumn red and orange; some drift down onto the water, where they float and leave gentle ripples. Low mist hangs over the lake and soft mountain silhouettes fade into the haze behind. A stone lantern stands beside the tree with a warm flame inside. Let the viewer interact: dragging across the water stirs the floating leaves and sends ripples through them, clicking the lantern makes it swing so its light sways across the water, and a dial turns the time of day from dawn through day and dusk to moonlight, changing the sky, the colour of the mist, the lighting and the reflections, with the moon and its reflection at night. Keep the mood calm and painterly, with a light wind moving the branches. Everything is built in code from Three.js geometry, shaders and materials; no external models or textures.

Build a Three.js scene: A small floating diorama chunk of island with a cliff cross-section shows layered rock, a palm tree, a wooden pier, a beached rowboat and a hidden treasure cave lit by a lantern. Waves lap the shore via a shader, gulls circle, and the palm sways. Click the X-marked sand to dig: sand particles fly and a chest rises and opens with a golden glow; the camera slowly orbits the floating base against a teal sky gradient.

Build a single Three.js page with five physics scenes and a scene switcher (buttons or tabs) to move between them; each scene can be restarted. 1) An explosion in a desert: a blast with a fireball, smoke, sand and debris thrown outward and falling back under gravity, and a shockwave rippling across the dunes. 2) A tornado: a funnel of swirling dust and debris over flat land that picks up small objects and spins them upward. 3) A balloon pop: a rubber balloon inflates, stretches and bursts, its fragments flying off and settling. 4) A water drop fall: a drop falls into still water, making a splash crown, a rebound jet, droplets and spreading ripples. 5) A Newton's cradle: five steel balls on strings where the end ball swings in and its momentum passes through the row, with believable collisions and slowly damped swinging. Make the motion physically believable (gravity, momentum, collisions, damping), light each scene well and label it. Everything is built in code from Three.js geometry, shaders and materials; no external models or textures. Build it as index.html (plus any local asset files you create) in the current directory. Three.js may load from a pinned CDN. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot.

Build "Millbrook Pond", a calm countryside pond diorama in Three.js, seen from above at a three-quarter angle. An irregular pond with soft grassy banks, rocks and reeds sits in a clearing ringed by trees and bushes, with a dirt path running around it. On one shore stands a small timber watermill cabin with a shingled roof and a stone chimney, and on its side a large wooden waterwheel turns continuously, its paddles dipping into the water and churning it. A plank dock juts out from the mill, a small arched wooden footbridge crosses an inlet, and a rowboat floats on the pond with a seated figure fishing, rod and line out; the boat bobs and drifts gently and the line's float makes small rings. The water is the star: a real-time reflective and refractive surface (a planar or render-target reflection of the mill, trees and sky; refraction of the shallow pond bed near the banks; depth-based tint from clear shallows to a dark centre) blended with a Fresnel term, soft normal-mapped wind ripples, and dynamic ripple rings from the waterwheel, the boat, the fishing float and the occasional rising fish, which spread and fade. Add gentle ambient life: swaying foliage, a few lily pads or drifting leaves, dragonflies or birds, and soft afternoon sun with shadows. The camera slowly orbits the pond on its own; the user can drag to orbit, pinch or scroll to zoom, and tap the water to make ripples, and a small unobtrusive control pauses the orbit and switches the time of day (for example afternoon and golden hour). The look is stylized and cohesive (low-poly or soft-shaded), and everything is built in code; no external models, textures or HDRIs. Also add a capture mode: opening index.html?capture=1 hides all UI and plays a scripted 12-second camera move around the pond that ends where it started, so it can be recorded as a seamless clip. Build it as index.html (plus any local asset files you create) in the current directory, with no build step; three.js and any addons may load from a pinned CDN. Aim for 60 fps on a laptop and at least 30 fps on a mid-range phone, with touch working. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot. Finish with a short README.md describing the controls and the capture mode.

Build an explorable tropical island in Three.js. The island has white sand beaches, palm trees, a green hilly interior and a small fishing village of wooden huts with thatched roofs, joined to the sea by a long wooden pier with boats moored alongside. The ocean around it is animated, with waves, foam along the shore and clear shallow water over a reef where fish swim among corals and sea plants, fading to deep blue further out. Let the player switch between modes: walk on the island, swim at the surface, dive underwater (with underwater fog and caustic light), sail a small boat around the island, and fly a free camera. Add a time-of-day panel with a slider that moves the sun from morning through sunset to night, changing the sky, lighting and water colours, with stars and lit windows in the village at night. Show the controls on screen. Everything is built in code from Three.js geometry, shaders and materials; no external models or textures. Build it as index.html (plus any local asset files you create) in the current directory. Three.js may load from a pinned CDN. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot.

Build a conceptual X-16 engine in 3D with Three.js: four cylinder banks, one crankshaft and exposed mechanics inspired by experimental multi-bank engine architectures. Make it animate (pistons, rods and crank moving in sync) with orbit controls. Everything is built in code from Three.js geometry, shaders and materials; no external models or textures. Build it as a single self-contained index.html in the current directory. Three.js may load from a CDN or be vendored. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot.

Write a single self-contained HTML file that plays an original animated short film, about 50 seconds long, drawn entirely in code.

Hard technical rules:
- One file: HTML + inline <script> (+ optional inline <style>). No external images, fonts, libraries, audio files or network requests of any kind. Every frame is drawn procedurally with Canvas 2D (or WebGL if you prefer).
- The canvas renders at a fixed internal resolution of 1920x1080 and is scaled with CSS to fit the window (letterboxed, black background).
- The animation starts automatically on page load and is driven ONLY by requestAnimationFrame and the timestamp from performance.now() (measure elapsed time from the first frame). Everything on screen must be a pure function of elapsed time t, so the film is deterministic and can be captured frame by frame. No Math.random() at draw time — use a seeded PRNG / hash noise so frames are identical run to run. No setTimeout/setInterval for animation.
- Define window.FILM_DURATION (seconds). After the film ends, hold the final frame.
- Soundtrack: write an original WebAudio score (melody, chords, a little percussion or ambience, and sound cues that match story moments) synced to the same timeline. Put ALL audio scheduling in a function window.buildSoundtrack(ctx, startTime) that schedules every note/effect on any BaseAudioContext (so it also works on an OfflineAudioContext). Also expose window.renderSoundtrack = () => an OfflineAudioContext(2, 44100*FILM_DURATION, 44100) render of it returning a Promise<AudioBuffer>. For live viewing, start the soundtrack on the first click/tap/keypress (browsers block autoplay) aligned to the current film time; show a small unobtrusive "tap for sound" hint until then. Use only oscillators, noise buffers you generate, filters, gain envelopes — no samples.
- No console errors.

The film (this is a showcase of what you can animate — make it genuinely beautiful and moving):
- An ORIGINAL story with a small emotional arc (setup, a problem or longing, a turn, a warm resolution). A single consistent main character — any character you like — who appears in every scene and is recognisably the same design throughout.
- At least 4 distinct scenes, with real transitions between them (e.g. wipes, iris, match cuts, cross-dissolves, camera moves through space).
- Expressive character animation: a proper walk cycle (legs, arms, body bob), blinking, and facial emotion changes (e.g. curious, sad, surprised, joyful) that follow the story.
- A virtual camera that pans, zooms and tracks, with parallax layers for depth.
- Lighting and time-of-day changes across the film (e.g. dawn → day → dusk → night, or a storm clearing), with colour grading, glows, and shadows.
- Particles and weather (rain, snow, fireflies, leaves, dust, stars — your choice, at least two kinds).
- On-screen story text / subtitles in a tasteful storybook style that tell the story in a few short lines.
- A cohesive art direction: a warm, hand-made "paper cut-out / storybook" look is welcome (textured paper, soft edges, slight wobble), but choose what serves your story.
- End with a title of your film and a gentle closing frame.

Koi Pond Garden: A calm, interactive Japanese garden seen from above at a gentle three-quarter angle, centred on a koi pond. The water must read as clear and refractive: you can see the pebbled pond floor and the koi through it, distorted by soft ripples, with caustic light patterns moving across the bottom and a subtle surface reflection and sheen. At least seven koi with detailed, varied patterned skin (kohaku, showa, ogon, tancho and similar), flowing fins and tails, swim naturally in smooth, unhurried curves, avoid each other and the pond edge, and occasionally rise near the surface. Surround the pond with natural stones and mossy rocks of varied shapes and textures, grasses, a few plants and flowers, floating lily pads (some with blossoms), and at least one small stone lantern or similar garden detail. Lighting should be warm and soft, with believable shadows.

Interaction: clicking or tapping the water drops a few food pellets that splash, float and slowly sink; nearby koi notice them, swarm toward them and visibly eat them (each pellet disappears when a fish reaches it), then disperse. At least two frogs sit on lily pads; clicking or tapping a frog makes it leap in an arc to another pad or into the water with a splash and rings of ripples. Clicking the water anywhere also sends out ripples. The camera can be orbited gently with a drag and zoomed within limits, but must not flip under the ground.

Build it as ONE self-contained HTML file with inline CSS and JavaScript. You may load three.js (and its addons) from a public CDN via an import map or script tag; no other external requests (no image, texture, model or audio files): make every texture and shape in code (procedural canvas textures, shaders or geometry). It must work when opened directly from disk in a current desktop or mobile browser, support both mouse and touch, fit the window responsively, keep a smooth frame rate, and run without console errors. Output ONLY the complete HTML file, starting with <!DOCTYPE html> and ending with </html>, with no explanation or markdown fences.

Make a 30-60 second animated video: one continuous zoom journey that starts on a single bacterium cell and keeps zooming in until it reaches the quantum fields the cell is ultimately made of.

The zoom passes through these scale levels, in this order:
1. the whole bacterium cell
2. the cell's internal structures (ribosomes, the coiled DNA of the nucleoid, the cell membrane)
3. molecules (for example the DNA double helix and proteins)
4. atoms
5. the nucleus of one atom
6. protons and neutrons
7. quarks and gluons, and finally the quantum fields they are excitations of

Requirements:
- One continuous shot: each level grows smoothly out of the previous one as the camera keeps zooming in; no hard cuts between levels.
- An on-screen label for every scale level with its name and approximate size (for example "Bacterium · ~2 µm"), shown while the journey passes through that level.
- Length between 30 and 60 seconds, 16:9 at 1920x1080.
- Sound: if you can make audio in this environment, give the video an original score or soundtrack that you create yourself (for example synthesized in code) and that follows the journey; do not use existing music. If you cannot make audio, leave the video silent and say so in your final message; a silent video is acceptable.

Remotion 4.0.527 is already installed for you in the current directory: node_modules is pre-installed and read-only, so do not run npm install or create-video, and a remotion.config.ts here already points rendering at the local Chromium. Render the final video yourself to out.mp4 in the current directory (for example npx remotion render <entry file> <composition id> out.mp4). You may render stills or frames and inspect your own output (headless chromium is available at /usr/bin/chromium) and iterate on your own before finishing.

Build a HyperFrames composition titled "Artemis II: Return to the Moon" — a

  and "What NOT to Do" list (no generic blues, no Roboto, no bouncy easing,
  no full-screen linear gradients on dark backgrounds).
- Use sub-compositions for each scene (scene-1.html through scene-7.html).
- Shader crossfade transitions between scenes (~0.6s each).
- All data counters deterministic (seeded PRNG if needed, no Date.now).
- Run `npx hyperframes lint` and `npx hyperframes validate` before finalizing.

HyperFrames 0.8.70 is already installed for you in the current directory: node_modules is pre-installed and read-only, so do not run npm install or npx --yes; use the local hyperframes command (for example hyperframes init <dir> --example blank, then hyperframes render). Render the final video yourself to out.mp4 in the current directory. You may take snapshots and inspect your own output (headless chromium is available at /usr/bin/chromium) and iterate on your own before finishing.

Build a hash table collision showdown: four hash tables of 31 buckets each receive the same stream of string keys (words like city names) at the same time, one insert per tick, using separate chaining, linear probing, quadratic probing and cuckoo hashing with two tables. Show each key flying in, the computed hash value as a number, every probe step as a hop between buckets, chains growing as stacks, clusters forming in linear probing (highlight primary clusters), and cuckoo evictions as keys being kicked out and flying to their alternate slot. Each panel shows live load factor, average and worst probe count, and total probes. When a table passes its load-factor limit (0.75 for open addressing, 0.9 for cuckoo, chaining never), animate a resize to the next prime size with every key re-hashed into place. Every 20 inserts, run a burst of 10 lookups (half present, half missing) and show their probe paths. Controls: key stream presets (city names, sequential numbers as strings, adversarial keys that collide under the default hash), choice of hash function (djb2, FNV-1a, a deliberately bad sum-of-chars), speed slider, play, pause, step, reset. So the page is alive without input, on load it starts streaming the city names automatically and after the stream finishes it waits 3 seconds and moves to the next preset, forever, until the user touches a control. Make it clear enough to teach and pretty enough to watch.

Save it as index.html in the current directory: one self-contained file with inline CSS and JavaScript only, no libraries or frameworks, and no external requests of any kind (no CDNs, web fonts, images or audio files). It must work when opened directly from disk, fit any window from a 390 px wide phone to a desktop, and run without console errors. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot.

Build a maze generation and solving show: four panels side by side (a grid on narrow screens) each carve the same-size 31 x 21 maze with a different generator at the same time: recursive backtracker (depth-first), randomized Prim's, randomized Kruskal's with union-find, and Wilson's loop-erased random walk. Show each generator's working state honestly: the backtracker's stack as a glowing trail, Prim's frontier cells, Kruskal's sets as distinct colours that merge as walls fall, Wilson's wandering walk with its loops being erased. Count steps per panel. When a maze is complete, solve it in the same panel with A* from the top-left to the bottom-right corner, drawing the open set, the closed set and the final path as a bright line, and show path length and cells explored. Then display a small comparison (generation steps, dead ends, longest corridor, solution length) so viewers see how the generators produce different textures of maze. Controls: maze size presets, speed slider, play, pause, single step, regenerate, and a toggle to solve with breadth-first search instead of A*. So the page is alive without input, on load it generates and solves automatically, then waits 3 seconds and starts a new round with a fresh seed, forever, until the user touches a control. Make it feel like a calm, hypnotic museum installation.

Build a pathfinding race visualizer: four copies of the same grid maze, side by side (stacked on a phone), where A*, Dijkstra, breadth-first search and greedy best-first search solve the same start-to-goal problem at the same time, step by step. Show each algorithm's frontier, visited cells and final path in distinct colours, and live counters for cells visited, path length and steps taken; when all four finish, show a small results table ranking them and say which found the shortest path and which explored the fewest cells. Controls: generate a new random maze (a perfect maze with some extra openings so paths differ), clear the grid, draw or erase walls by dragging on any grid (the edit applies to all four), move the start and goal by dragging them, a speed slider, play, pause and single step. Diagonal moves are off; every move costs 1. So the page is alive without input, on load it generates a maze and starts the race automatically, and when a race finishes it waits 3 seconds and runs a new maze, forever, until the user touches a control. Make it clear and beautiful, the kind of visual a teacher would put on a projector.

Build a working browser music studio in one page, in the spirit of a classic drum machine plus a tiny DAW. It needs: an 8-track by 16-step sequencer (kick, snare, closed hat, open hat, clap, tom, bass, lead) where every sound is synthesized with the Web Audio API (no samples); per-step velocity (click or tap cycles levels) and per-track mute, solo, volume, pan and a simple filter knob; a piano-roll editor for the bass and lead tracks over two octaves; tempo (60 to 180 BPM) and swing controls; four pattern slots A to D with a song arranger row to chain them; a master section with a compressor and a visual spectrum analyser and waveform scope driven by an AnalyserNode; transport with play, stop and a playhead that lights each step in time; and export of the current pattern as JSON plus import from JSON. Audio must start only after a user gesture (show a clear Start audio button), but the visuals must not wait for it. Seed it with four good-sounding patterns that make a short song. So the page is alive without input, on load it runs the sequencer silently in demo mode with the playhead moving, steps lighting, the scope and spectrum animating from the synthesized signal (route audio to the analyser but keep the output muted until the user presses Start audio), cycling through the four patterns and occasionally toggling steps as if someone were jamming, until the user touches anything. Make it look like premium music hardware: knobs, LEDs, tactile buttons.

Build a working photo editor in one page in the spirit of Lightroom. Since no image files can be loaded from the network, first render a detailed photo-like scene procedurally onto a canvas (a mountain lake at golden hour with sky gradient, clouds, layered mountains, reflections, trees and noise grain), and also let the user open their own image file from disk. It needs non-destructive editing with a full adjustment panel: exposure, contrast, highlights, shadows, whites, blacks, temperature, tint, vibrance, saturation, clarity, a tone curve editor with draggable points per channel, HSL sliders per colour band, vignette and grain; crop and straighten with rule-of-thirds overlay and aspect presets; a live RGB histogram; a before and after split view with a draggable divider; preset looks (cinematic teal-orange, faded film, black and white high contrast, moody) that can be applied and then tweaked; full undo and redo history listing each step; and export to PNG. Processing must stay responsive: work on a preview-size buffer while dragging and render full resolution on release. So the page is alive without input, on load it runs a scripted demo: slides exposure and temperature, bends the tone curve, applies two presets, drags the before and after divider back and forth, crops, then resets and repeats with different settings, until the user touches anything. Make it look like a pro tool: dark UI, precise controls.

Build a working 1990s-style desktop operating system inside one web page. It needs a desktop with a wallpaper and icons, a taskbar with a start button, a start menu and a live clock, and real windows: each window can be dragged by its title bar, resized from its corner, minimised to the taskbar, maximised, restored and closed, and clicking a window brings it to the front. Include three working apps that open in those windows: a Notepad that edits text and saves to and reopens from localStorage under a file name; a Paint app with a pencil, brush sizes, a 16-colour palette, a flood fill and an eraser on a canvas; and a Calculator with the four operations, decimals, clear and a keyboard input path. Double-clicking a desktop icon or choosing an app from the start menu opens it. Several windows of the same app can be open at once. Everything is drawn with HTML and CSS (no images): bevelled grey buttons, a classic title-bar gradient and pixel-crisp borders. So the first view is not an empty desktop, on load the system shows a short boot screen (about 2 seconds) and then opens Notepad with a welcome note and the Calculator, cascaded. On a phone, windows open maximised and the taskbar stays usable.

Build a working mini spreadsheet app in one web page. It needs a grid with column letters A to Z and row numbers 1 to 50, a formula bar that shows the raw content of the selected cell, and editing by typing or double-clicking (Enter commits and moves down, Tab moves right, Escape cancels, arrow keys move the selection). Cells hold numbers, text or formulas starting with =. Formulas support + - * / and parentheses, cell references (A1), ranges (A1:B5) and the functions SUM, AVERAGE, MIN, MAX and COUNT; every dependent cell recalculates instantly when a referenced cell changes. Show #REF! for a bad reference, #DIV/0! for division by zero and #CIRC! for a circular reference instead of hanging. Support selecting a rectangular range by dragging or shift-clicking, with a status bar showing that range's sum, average and count; copy and paste within the grid (references in pasted formulas shift relative to the move); bold and number-format buttons (plain, 2 decimals, currency, percent); and a save to and load from localStorage. So the first view is meaningful, on load the sheet opens with a household budget already filled in: twelve expense rows with monthly amounts, a total row and an average row built with formulas, and a percent-of-total column built with formulas, all computed live. Make it look like a clean modern spreadsheet that is usable on desktop and phone.

Build a working team chat app in one page in the spirit of Slack. It needs: a workspace sidebar with channels and direct messages, unread counts and bold unread channels; a message view with grouped messages by author and time, day dividers, avatars drawn as coloured initials, markdown-lite formatting (bold, italic, inline code, code blocks, links rendered as text), emoji reactions with counts that toggle on click or tap, threaded replies in a side panel, message editing and deletion, @mentions with an autocomplete popup, and a composer with Enter to send and Shift+Enter for a new line; a search box that finds messages across channels and jumps to them; typing indicators; and persistence to localStorage. Simulate four teammates as small scripted bots who reply in character after a delay when mentioned, react to messages, and occasionally start threads, so the workspace feels alive. Seed the workspace with realistic history for a small startup team (general, design, engineering, random channels). So the page is alive without input, on load it runs a scripted demo: switches channels, types and sends a message with a mention, a bot shows a typing indicator and replies, reactions appear, a thread opens and gets a reply, a search finds an older message, and the loop continues with new conversation every 30 seconds, until the user touches anything. Make it polished, friendly and fast.
