From the README

An interactive WebGL fluid experiment exploring the unstable boundary between gesture, color, and simulated flow.

Natural Instability is a fullscreen WebGL fluid interaction. Drag your pointer across the canvas and your gesture is translated into a flowing trail of ink; a quick tap releases a single ink drop. Two color families — the ink itself and the trail it leaves behind — mix as you move, and the result drifts on its own once you stop.
