This simulation implements the Gray-Scott model, where two chemicals interact and diffuse to create self-organizing patterns. Alan Turing showed in 1952 that such systems could explain morphogenesis—how organisms develop their shapes and patterns.
The Gray-Scott equations describe how the concentrations of chemicals A and B change over time:
Where ∇² is the Laplacian operator (measuring diffusion), AB² represents the reaction rate, and the system exhibits pattern formation when the activator (B) diffuses slower than the inhibitor (A).
