Conway's Game of Life

This is my first project using the pygame library. It came together rather quickly, but my algorithm needed some optimization. So after iterating over my code, I managed a 5x performance improvement. To see all the available command line arguments: Life.py --help My favorite settings: Life.py --gridsize=256 --numcells=10000 To profile the code as I did use: Life.py --gridsize=256 --numcells=10000 --profile I feel my implementation is pretty optimized. But if you know of any other optimizations, please comment on my blog to let me know about them. Thanks.
