Hmm... seeing the attached picture would be easier if there _was_ an
attached picture, don't you think ? :D

Oh, thank you very much, but I think I would do that with an external
little program (that would probably run a lot faster than povray) that
would generate the scene. If I do that quickly, I will keep you aware of
that !
But yes, go on, please.

Yep, certainly :) Thanks !

It might be interesting to start with an image of your name and see what
that looks like three generations down the line.

Well I posted it, maybe someone else is interested. I've already
done a program which could probably have been modified to output something
usable by POV, but I'm not very experienced at parsing external files with
it... and it was funnier to do it completely with POV :D

I like the idea. I remember looking at some CA stuff a few years ago.
There's a fantastic book related to the subject called:
Growing Artificial Societies: Social Science from the Bottom Up
The book takes you through various algorithms that can used in a CA
environment to simulate various social behaviours. I even wrote my own
VB program to run some of the simulations. It would be great to convert
this to POV, as then you could create some stunning animations!!

Why don't you do this:
#declare Foo=array[3][3]
{
{1,2,3},
{4,5,6},
{7,8,9}
}

Because I didn't want to have something fixed like this. To change the
size of the world with this system you would have had to completely change
the declaration of the array... and directly editing 30x30 arrays like
this isn't really convenient.
This isn't a problem anymore anyway, since the starting values can now be
taken from a picture.

Hi!
The moment I saw this, I knew that I must try to code that myself. So I did. Here is
one of my images. More at

Also very cool. I need to scrounge the time to build an animation of
Life growing. R-Pentamino, anyone?

In most cases outputting the final SDL as an include-file from your
program is the easiest way to go.
