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.

You always seem to arrive at these things so casually. Like you back
into the discovery while doing something else.
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 :)
