Reaction-Diffusion — Labyrinthine Stripes & Spot Transition

Feed f: 0.037 Kill k: 0.060 Steps/frame: 8 Reset random Pause step: 0

Gray-Scott reaction-diffusion model: ∂u/∂t = D_u∇²u − uv² + f(1−u), ∂v/∂t = D_v∇²v + uv² − (f+k)v. Sweep feed rate f and kill rate k to transition between spots, stripes (labyrinthine), worms, and chaos.
