Presets
Excitable Medium
quiescent — drag to inject a stimulus and watch oxidation fire, sweep outward, and recover
Pacemaker
a steady source rings out concentric waves of oxidation that collide and annihilate
Spiral Wave
ε=0.020 — a torn wavefront curls into a rotating chemical vortex
Spiral Turbulence
scattered wavebreaks spawn dueling rotors that collide, split, and reform — chemical chaos
