• feed rate (f)0.055
• kill rate (k)0.062
• diffusion (a)1.00
• diffusion (b)0.50

§README

1. §01Gray–Scott parameters f / k can be tuned to grow stripes, mitosis, coral or U-Skate behaviour. This preset is calm mitosis.
2. §02Click the canvas to reseed — the existing field is wiped and re-grown so you can step through phase space.
