The famous Zero-Player Game, the game of Cats...? Really satisfying to watch btw. Update v1: Added population control and children/birth. Now it's more of a game then a simulation so changed name to The Game of Cats. Update v2: Set children/birth to random and added better population control. Added line graph of clones on each frame. Added clone count. Update v3: Removed line graph and updated population control once again. Tweaked some rates. Set children/birth to 2 again.
