It's as easy as Pascal's triangle, and only gets better from there.

Sometimes that is the case. This time I had made the discoveries some
time ago, but never put them together to produce an image like this one.

I know it can, because I managed to do it. Attached is an example of the
pattern so far. This is just one of many possibilities. This particular
image exhibits the pattern's ability to exceed POV's 256 entry limit for
the color_map function. I can exceed that number vertically, but not
horizontally, for to do so might eat too much memory. I can make really
long strips with this, a total of 255*128 cells. This one, stretched
out, would be only four times its current height. Rendering the full
length version caused my computer to start swapping the hard drive
earlier today.

Yes. To make it "physical" you could use inside() tests to check space
for previously placed cells. By doing this you could break free of the
usual grid restraints.

I don't think I've seen anything like this in p.b.i--it's so different and
beautiful that it seems like a 'new direction' for POV-Ray. This has "Hall of
Fame" written all over it. I can't begin to imagine how you accomplished such a
work of art; it's sublime, and transcends technique.

Probably something like a CA, only implemented in biological chemistry.

Well, is it any surprise that organisms comprised of cells exhibit some
"cellular automaton" behavior? ;)

To quote from
http://www.sciencedaily.com/releases/2006/11/061126121128.htm
Biology reveals that the shape and colour patterns on the shell of the
mollusc mirror the localised expression of specific genes in the
mantle, a layer of skin situated just below the shell.
For rendering shells in POV you could look at http://www.shelly.de/
I have not tried this program though.
The isosurface tutorial has some renderings
http://www.econym.demon.co.uk/isotut/shells.htm
I am sure i saw an article some time ago that gave equations enabled
you to draw the patterns of actual shell colourings but cannot
remember where that was.

Well I didn't coin it - just adapted it from Mr Wolfram and his CA opus
"A New Kind Of Science".
