Particle Life
A few simple attraction rules between colors give birth to cells, worms and swirling ecosystems — no biology, just physics.
The grid at top-left is the rule book: each row is a species, each column the species acting on it. Green means attracted, red means repelled, brighter is stronger. The grid is not symmetric, so one colour can chase another that flees it. Click a cell to set a rule.
