I love the fact it's an 'around the world' canvas. Most implementations I've played around with use an expanding or fixed width one instead...it makes some combinations truly amazing.

For example, the acorn pattern(http://en.wikipedia.org/wiki/File:Game_of_life_acorn.svg) is a lot more impressive, because the gliders spawned travel across the screen and interact with the solid blocks. Empirically, it seems to make the pattern last a lot longer!
