This is gitlife. It takes the nifty contributions calendar from a GitHub user's profile and turns it into a simulation of Conway's Game of Life. It's still a bit rough around the edges. The biggest problem currently (sans interface, design, etc.) is stopping the simulation once it is composed entirely of oscillators and/or still lifes (AKA nothing interesting is going on anymore). However, it's coming along nicely, so I've put it up here.
