a generative morphogenesis
Two chemicals — one that builds, one that dissolves — diffuse through a featureless medium until it breaks its own symmetry into form. This is Turing's morphogenesis, and it is also the Tao giving birth to the ten thousand things: activator and inhibitor, yin and yang, arising into pattern without being forced. As the field self-organizes it drives down its free energy — the rate at which it still surprises itself — settling into the shape that evidences it. Wound the pattern with your cursor and watch it navigate back toward its own form.
click and drag on the field — wound it, sow it, and watch it heal
