Zoom, inline player and more ways to view
The model's own page, run in a sandboxed frame only when you ask (a page that needs its own origin opens in a new tab on a separate demo site). Phones get a full-screen player capped at 1.5x pixel density (2x on larger screens) so it stays smooth; the original page runs uncapped. It starts in its auto-tour (T switches to play mode on a keyboard).

No rubric for this prompt
Visitor votes and reviewer grades are not available yet.
- AI judge
- AI judge: the test runner (model claude-opus-5-5), scoring by visual review of the 1600 px render against the pre-registered rubric. No AI-judge score exists for this result: there is no rubric for this prompt, so no score is shown and none is made up.
- Visitors
- Public voting with a blind reveal is coming: you score the output first, then see the other scores.
- Reviewer
- The reviewer's own grade appears here once it is added.
Scores compare results for the same prompt only. AI-judge boards rank runs within one prompt, equal totals sharing a rank; scores from different prompts are never averaged.

The exact prompt
as run, 927 characters. Every result for this prompt
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.
