Excitable

Category: Simulations Tags: simulation, reaction-diffusion, spiral, organic, hypnotic, gpu, audio, glow

Reaction-diffusion excitable medium — Barkley/FitzHugh-Nagumo spiral and target waves crawl and rotate across a persistent chemical field, nucleating new spiral cores on the beat. Never settles, never loops.
