Hello folks.
Was messing around with Mike Davis' Conway code, and decided to see how it works in 3d with cubes. Often it initially produces some interesting patterns, but then gets pretty chaotic. Here's the code anyway, it requires the PeasyCam library but if you comment those few lines out it will still run fine.
If anyone has any more suggestions on how to get better results and/or spot any mistakes do let me know!
