Pilot
Interactive demo: pilot reaction-diffusion
This simulation runs entirely in your browser, on WebGPU. Launch a preset, adjust F and k to cross the boundary between regimes, or paint V with the brush to seed the reaction wherever you like.

WebGPU isn't available here
This interactive demo needs WebGPU, which your browser doesn't support (or has disabled). Try a recent Chrome, Edge, or Firefox on desktop. In the meantime, here's a capture of a Gray-Scott run (spots, F=0.037, k=0.060).

Tip: click-drag on the grid to seed V (and remove U locally) with the gaussian brush.
