Diffusion-limited aggregation: particles wandering at random until they touch and stick, which cannot help building a fractal of dimension 1.71 — the same shape as an electrodeposit, a mineral dendrite and a bacterial colony; the sticking probability follows the level and a drop releases a swarm.
Drawn with: a WebGL2 shader.
Reacts to and looks like: gpu, webgl2 and audio-reactive.
Family: Visualiser.
