Tune
Two reacting, diffusing chemicals grow into islands and labyrinths. Watch cells spread, divide and meet, then scrub back to a composition worth keeping.
Gray–Scott reaction–diffusion · concentration contours
A seeded, fixed-step Gray–Scott simulation on a 112 × 112 periodic grid. Feed and removal rates choose a regime; contour lines trace chemical concentration. Playback evolves the simulation to a final frame and stops. Rewinding restores the same state, rather than reversing the chemistry.
