Beyond the Game of Life

I had the idea of 3D life where every other cell is unused (chess-like); then every cell has 8 neighbors, but in 3D. But it seems that life rules make this space stable. Didn't experiment with other rulesets.
I've never seen a simulation of Game of Life in several levels; it's yet more impressive than I thought Game of Life could be per se.
I only created 3 plugins for it, but one of them was similar to the picture in the article, where each new round of evolution is placed on top of the previous level.
Here's a screenshot: http://jlarocco.com/crap/3d_life.jpg
If you're interested, the code is up on GitHub. It should work out of the box on Linux, but I was having some problems getting the plugin shared libraries to build and load on all platforms. I think OSX works, but it might still require copying the plugin shared libraries into the .app. Don't know if it works on Windows.
