🧪 2D Reaction-Diffusion (Gray-Scott) - Feed/Kill Map and Turing Patterns

2D Gray-Scott reaction-diffusion on a periodic lattice: paint chemical B, choose spots, stripes, mitosis or coral on a live feed/kill map, and compare the measured pattern wavelength with the linear Turing prediction.

ControlsFeed rate (f) and kill rate (k) sliders (0.01-0.1 and 0.03-0.075) directly tune the PDE parameters; a speed slider sets PDE steps per animation frame (1-24). Five presets (Spots, Stripes, Mitosis, Maze, Coral) jump to known f/k combinations and reseed the grid. A palette selector recolors the display, Reset grid reseeds from the centre, Add seed drops a fresh random blob, Pause freezes the simulation, and clicking or dragging on the canvas injects chemical V at the cursor.
