⚠ Work in progress: the geometry is drawn, not solved on. The solver still uses the round sphere's Laplace–Beltrami operator, so on other shapes you see the sphere's pattern painted onto that surface.
Reaction-diffusion on closed surfaces, solved live with spherical harmonics on WebGPU via shtns-webgpu. Both the solver and the shape are the MATLAB below, compiled in your browser by numbl. Edit either and watch it change. Drag to rotate.
