The Ink Has Opinions
A reaction-diffusion postcard: two imaginary ingredients react and diffuse on a 96×96 dish until spots, coral or mazes appear. Click the dish to plant a spot. Same seed and preset regrow the same starting conditions — the live pattern keeps evolving after that.
This is a Gray-Scott illustration on a small grid with fixed presets — pretty chemistry-flavored math, not a model of any organism, material, or experiment. Sharing copies a link with the seed and preset (the starting conditions); to keep the current pattern exactly, save the PNG.
