isiliconx / spacebunny
A space bunny on the Moon, eight GPU graphics demos, and fifty more self-contained projects — every scene generated procedurally at runtime, no external assets, no network.
A complete three.js game on the WebGPU backend.

Collect 14 helium-3 crystals across a procedurally eroded lunar basin, then plant the mission flag. Articulated bunny rig, asymmetric lunar gravity, terrain-aware camera, footprints baked as real pits.
Eight self-contained WebGL2 pieces. Each is a single HTML file with no CDN, no build step, and no network access — open one straight from disk and it runs.
Fifty more pieces, one per agent. Each is a single self-contained file with its own renderer, controls, and diagnostics.
No projects in this category.
The demos were authored in parallel by a fleet of agents, then verified by rendering each one headlessly and measuring the result.
A screenshot proves something drew, not that it drew correctly. Every
demo sets window.__ready when its scene is live, and a
small CDP harness waits for that flag, captures the frame, and reports
colour count, clipping, and tonal spread. Verdicts are objective.
An inverted SDF sign collapsed an entire terrain to one flat plane. A pressure solver rendered into the texture it was sampling. sRGB colour values clamped as linear light turned every soft body pure white. All four presented as "looks slightly wrong" and all four were logic errors — only a render could catch them.
One demo was a featureless white disc. The cause was a 640×400 internal buffer — below one pixel per filament — plus exposure parked on the tonemap shoulder, where small input changes do nothing. A sweep scored candidates on tonal spread rather than brightness. 3,718 → 11,699 colours.
The verification harness lives in demos/tools/: a
zero-dependency CDP renderer, an image health checker, a tiling
detector, and a static self-containment audit. Run
demos/tools/verify_all.sh to re-verify all eight in about
eight minutes.
