Using the pre-provided three.min.js (global THREE), render a full-screen scene with a rotating icosahedron lit by two colored point lights, orbit-style auto-rotation, and a subtle starfield background.

The user wants a single-page web app (index.html) that uses three.min.js (already present in the workspace) to create: 1. A full-screen scene 2. A rotating icosahedron 3. Two colored point lights 4. Orbit-style auto-rotation 5. A subtle starfield background Let me first check that three.min.js exists in the current directory, then create the index.html file.

Good, three.min.js is present. Now let me create the index.html file with all the required features.

The file has been created. Let me verify it's present and well-formed.

The file is created successfully. Let me verify the HTML file is well-formed and contains everything we need.

Everything looks good. Let me give a summary of what was built.
Done. `/workspace/index.html` is a fully self-contained single-page app that uses the local `three.min.js`. Here's what it renders: - **Full-screen WebGL scene** — dark background (`#050510`) with ACES filmic tone mapping - **Rotating icosahedron** — `IcosahedronGeometry` with metallic `MeshStandardMaterial` (flat shading), plus a subtle blue wireframe overlay via `EdgesGeometry` - **Two colored point lights** — a cyan light (`#44ccff`) and a magenta light (`#ff44aa`), both slowly orbiting the scene on different paths/frequencies for dynamic color shifts - **Orbit-style auto-rotation** — the camera orbits the origin at a gentle pace while the icosahedron spins on all three axes - **Subtle starfield** — 2,000 particles on a distant sphere shell with per-star size variation, additive blending, and a twinkle effect driven by a custom vertex/fragment shader No network requests, no external dependencies — just `three.min.js` loaded via `<script src="three.min.js">`.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.

EVALUATION
Rotating icosahedron with pink/blue point lights and faint starfield, animates continuously but stays small and centered.
Vision grade · anthropic/claude-sonnet-5
MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
