Here is a 'glider' in a 3d version of the Game of Life.
(all POV script)

It looks more like a bug :)

Tell me about the rules, Please? Or a link? I know about the 2D 
version...

I'll put scene file and include file in povray.binaries.scene-files soon.
In 3d, a 'cell' has 26 neighbors. The rules for the glider animation were
just
"if a 'dead' cell has 5,6, or 7 live neighbors, it becomes 'live', and if
a 'live' cell has 6 live neighbors it survives to the next generation".
You can see the include file for the initial arrangement for 'glider5766'.

Are there 'static' formations like classic clocks and things like that?  What 
does a large formation look like over time?  Can you associate a density color 
with formations?

In 2d there are the classic 'Conway' rules. So far as I know, there is no
standard set of rules
for 3d. With certain rule sets you can get static formations and gliders and
blinkers, etc.
So it seems pretty wide open for experimenting.
But a problem with my POV implementation is that once the 'playing field'
gets large, the
computation time gets unacceptable if the goal is experimenting, like
looking for forms that
'do stuff'.

Damn.  Yet another cpu bounded situation.  What we need is a massive cluster 
of computers all rendering frames.  But we can't because the GOL frame depends 
on the previous frame.  Each system would need to render a few lines only and 
then assemble the image and then move onto the next frame.

I have a stack of systems that just sit around and collect dust.  I've always 
wanted to get sixteen of them going simutaneously but the scripting would be a 
bit nasty and the assembly of the image even nastier.

Just thinking and typeing at the same time.
