LIT Creature Forge is an evolution simulator based on Karl Sims' 1994 paper "Evolving Virtual Creatures." Run generation. Watch 200 random body plans try to walk. The ones that move farthest reproduce, with mutations. Run another generation. Repeat until something organic crawls out of the chaos. There is no design tool. There is no creature editor. Bodies, sensors, brains, and gaits all evolve together — no human input.
