A real-time 3D scene drawn by one fragment shader. There are no meshes and no 3D engine: every pixel shoots a ray into a mathematical description of the scene.

The JavaScript side is tiny: it draws one triangle that covers the screen, passes time and camera angles to the shader, and lowers the resolution automatically if your GPU can't keep up.
Drag to orbit · scroll to zoom · Change mood swaps the lighting. It slowly orbits by itself when you leave it alone.
