Beautiful.
I've wondered before about ways to realistically texture mollusc shells, and
this appears to be it! It might not even be too far from how it actually
happens in reality.
I too would be interested to see a blob version.

Oooh.
Beautiful both the image and the concept.

Actually, I recently replaced several thousands of randomly placed spheres in
some scene with blobs, not for "blobification" but just for speedup. Seems like
the internal bounding of blobs is significantly more effective than the standard
boxing approach.
But that may also differ depending on other circumstances; for instance, those
spheres were scattered quite sparsely about, so the main load was not to
compute intersection points, but to verify that no intersection points had to
be computed in the first place.

Wolfram, move over. Very pretty.

Intriguing in the possibilities hinted at. Could 'Cellular Automata' be
implemented as a POV procedural pattern?
Could the building blocks be actual building blocks, like bricks or
something?

I sometimes wonder how certain shells have come to have such patterns on
them. There is one CA sim based on Pascal's triangle which produces
Sierpinki-esqu patterns, and I have seen something strikingly similar on
a real shell. How does it happen?

It might just happen :)

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.
