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).
Recorded from the live demo (stepped clock). Preview video recorded by this site from the live demo. The moving picture above is that preview; the button runs the real page.

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.

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. #vibejam 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.

- Total reported by the harness
- none
Computed from harness-reported token counts x list prices. DeepSeek bills no cache writes (a cache miss is input), so cache_write is 0; dsh prints no dollar figure.

Run notes
- frozen prompt (reconstructed): recovery/prompts_recovered/folding_road_threejs.assembled_candidate.txt: verbatim ask + recorded harness suffix
- dsh has no terminal UI: headless mode (TUI not automatable), run in tmux for screenshots
- dsh session log decompressed from session.v3.jsonl.zstd
- Run on a GitHub Codespace (codespaces lane of box-fleet); model calls reached the providers through a credential relay on the home machine (no keys in the codespace).
- Mode: headless mode (TUI not automatable) — dsh --profile headless in tmux, inside bubblewrap
- Isolation audit: outside paths seen
