Voice-Grown Patterns

Zebra stripes, leopard spots, fish-skin patterns and spiral waves can all grow on their own from two chemicals that react and diffuse. Here, your voice rewrites the equation’s parameters in real time.

∂u/∂t = Dᵤ∇²u − uv² + F(1−u) · ∂v/∂t = Dᵥ∇²v + uv² − (F+k)v

Pitch chooses which pattern family to slide along; volume raises k and makes the pattern “melt”; low frequencies speed up diffusion and drop new seeds on each beat.
