Both files exist, I'll check the HTML file next.

Created `index.html` (8.8 KB) alongside `three.min.js`. The scene includes: - **Rotating icosahedron** — flat-shaded metallic surface with subtle blue wireframe overlay, spinning on both axes - **Two colored point lights** — cyan (`#00ffff`) and orange (`#ff6600`), each orbiting the mesh on independent paths, with visible marker spheres - **Orbit-style auto-rotation** — camera slowly orbits the icosahedron; drag to manually orbit, scroll / wheel to zoom - **Starfield background** — 2000 additive-blended stars with soft radial sprites and color variation, slowly rotating - **Full-screen responsive** canvas with resize handling and touch support

EVALUATION

4/5 working

Rotating icosahedron lit by cyan and orange point lights with starfield background, auto-rotates and reacts to zoom/scroll (zoom is main effect of inputs).

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.
