PS5 Pro DualSense controller (max-fidelity SVG)

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.

Cinematic fjord boat scene (Three.js)

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).

Output ONLY the complete index.html, starting with <!DOCTYPE html> and ending with </html>, with no explanation and no markdown fences. 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 until it looks genuinely cinematic before finishing. Close any browser you open as soon as you've taken your screenshot.

Creature robot blueprint

Design a giant desert sandworm re-engineered as a robot, presented as an engineering blueprint. Deliver ONE self-contained index.html (SVG and/or canvas, inline CSS and JS, no external assets, libraries or fonts). It must include: an animated robotic worm that moves through sand, with segments that articulate as it burrows and surfaces; a labelled segment-by-segment mechanical breakdown (for example head and mouth assembly, drive segments, sensor ring, power core, tail) with callouts naming each part and what it does; a cross-section diagram of the mouth showing the grinding and intake mechanism; and a terrain and operations map showing the worm's route, depth and working zones. Everything must share one cohesive blueprint style: blueprint-blue background, white and cyan line work, grid, dimension lines, title block and technical lettering. It must look good on desktop and phone. Write everything into the working directory and finish with a short README.md.

Game battleship

Build a complete, polished Battleship game playable in the browser (index.html plus any JS/CSS, no build step). Player vs computer on 10x10 grids: ship placement (drag or click, with rotate), a computer opponent with a sensible hunt/target strategy, hit/miss/sunk feedback with animation and sound, turn indicator, win/lose screen and restart. It must work with mouse and touch and look good on desktop and phone. Write everything into the working directory and finish with a short README.md.

Gpu fluid sim

Build a GPU-accelerated fluid simulation in a single HTML file using WebGL, no external libraries. Dragging the mouse or a finger should push colorful dye through the fluid, with a soft glow. Make it look stunning and run smoothly.

Build it as a self-contained index.html in the current directory, with WebGL/WebGL2 shaders you write yourself; no libraries and no CDNs; interactive with mouse or touch input. 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.

Humanoid motion cycle

Build a single-page Three.js scene (one index.html file, no build step, three.js from a pinned CDN) with a rigged humanoid character (a procedural skeleton and simple body meshes are fine) that plays walk, run and jump cycles, with on-screen buttons or keys to switch between them and blend smoothly from one to the next. The motion must look human, not spider-like: respect realistic joint limits (knees and elbows bend one way only, no joint rotates past a human range), feet plant on the ground with no sliding while in contact, the pelvis bobs and the torso stays upright with natural counter-rotation of shoulders and hips, and arms swing opposite to the legs. Include a ground grid, an orbit camera and a toggle that shows the skeleton. It must run at 60 fps in a desktop browser and work with touch. Write everything into the working directory and finish with a short README.md describing the controls.

Threejs artwork style pass

# 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.


Deliverable: reply with exactly one complete, self-contained `index.html` file in a single ```html code block. Requirements:
- Use three.js (r160 or newer) loaded from a CDN through an `<script type="importmap">` (e.g. jsDelivr or unpkg); addons such as OrbitControls may be imported from the same CDN via the import map.
- No other files: no external textures, models, fonts or images. Generate any textures procedurally in code.
- It must run by simply opening index.html in a modern desktop browser, fill the window, and handle resize.
- Animate with requestAnimationFrame and a clock, so it looks right at any frame rate.
- No explanation is needed outside the code block.

Threejs mechanical bee

# 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.

Threejs procedural armor suit

Build a single self-contained index.html using Three.js (imported from a pinned CDN; no external models, textures or other assets) that shows a full humanoid powered-armour suit built only from code: primitives, extruded shapes, lathes and generated geometry. Aim for 500 or more distinct mesh parts (plates, joints, pistons, vents, bolts, cables, lights) with a coherent, detailed design and good materials and lighting. Include an assemble / explode animation (parts fly in and lock into place, and can be exploded back out), a sci-fi HUD overlay (targeting reticle, part labels that track parts on screen, a system status panel), orbit controls, and buttons to trigger assemble and explode. It must run smoothly and work with touch on mobile. When the suit is built, log the total number of distinct mesh parts to the console as: PART_COUNT <n>. Write everything into the working directory and finish with a short README.md.

Threejs slime softbody

Build a single-page Three.js scene (index.html, no build step, three.js from a pinned CDN or vendored) showing a glossy translucent slime/jelly blob resting on a floor. It must behave as a soft body: clicking or dragging pokes and squishes it, it wobbles and settles with visible jiggle and damping, and it casts a soft contact shadow on the floor. Include subsurface-like translucency, specular highlights, and a small UI to reset and to drop the blob from height. Target 60 fps on a mid-range phone; mobile touch must work. Write everything into the working directory and finish with a short README.md describing controls.

Threejs stillwater pond

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.

Blender humanoid walk cycle

Using Blender's Python API only (a script run headless with blender -b -P), build a humanoid character with an armature (hips, spine, neck, head, arms with elbows and hands, legs with knees and feet) skinned to a simple stylised body mesh, and animate a seamless looping walk cycle of 32 frames at 24 fps. The walk must look human: knees and elbows bend one way only within realistic joint limits, feet plant with no sliding during contact, the pelvis bobs and the torso stays upright, and arms swing opposite to the legs. Add a three-point light and a camera. Render a 1280x720 PNG still of a mid-stride frame to render.png, render a turntable video to turntable.mp4 (the character walking in place while the camera orbits once around it, 1280x720, 24 fps, at least 4 seconds), save scene.blend, and export walk.glb with the armature and the walk animation (no cameras or lights). Write everything into the working directory.

Blender spongebob

Using Blender's Python API only (a script run headless with blender -b -P), model SpongeBob SquarePants as a stylised 3D character: porous yellow sponge body, white shirt, red tie, brown square pants, big eyes with blue irises, buck teeth, thin arms and legs with white socks and black shoes. Use real material colours (Principled BSDF base colours, not procedural-only) so the model keeps its colours when exported. Add a simple three-point light and camera, render a 1280x720 PNG to render.png, save scene.blend, and export model.glb (apply modifiers, no cameras or lights). Write everything into the working directory.

Video printing press collage remotion

[Task]
Create a 60-second motion-graphic explainer video on the history of the printing press, from its origins to the present day.

[Roles]
- Higgsfield: creates every image in the video (still images only).
- You: create all motion graphics and animation.

[Style]
Newspaper cutouts with mixed-media collage, highly polished: layered paper cutouts, torn edges, halftone textures, soft shadows, and bold editorial typography.

[Rules]
- Keep every fact and date accurate.
- No text inside the Higgsfield images. Add all text yourself as animated typography.
- Keep the look consistent across every scene.
- End on the opening frame so the video loops. Never end on a hard cut.

[Harness notes] Images come from the image-generation tool available to you (still images only). Render the final video to out.mp4 (1920x1080, 60 s). Write everything into the working directory. 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.
