The Gray-Scott model: just feed rate and kill rate, two diffusion constants, and a simple reaction. From these, Turing patterns emerge — spots that divide, coral that branches, labyrinths that wind, waves that pulse. Click anywhere to seed new chemical. Adjust parameters to cross phase boundaries between radically different forms. The same equations produce all of them.","shortDescription":"Turing patterns from simple chemistry"}}
