In (my implementation of) Conway's Game Of Life you can "draw" cells and start the game whenever you want. Some cells will survive, some will die and most of the time you won't be able to predict who's going to make it. You can build anything from gliders to entire spaceships, glider generators to spaceship generators and much more, explore this for yourself and be creative! Of course you can also rebuild things that other people built to try them out for yourself :)

 I'd be happy about a rating and suggestions for improvement!
