I have attached an image of a sphere with a crackle pigment. As you see,
it has separate "cells". In the official version and MegaPOV, these are
located randomly, I was wondering if it would be possible to specify
their locations and strengths manually, maybe as an extension to the
blob pattern.

No, though it could be used to do that if you wanted(and if you figure
out what a 3D Fibonacci pattern is).

It's from the lower left image on this page:
http://www.wadhome.org/frazetta/overview0002.html
I don't know how Frank Frazetta look(ed ?), but
if it is showing him, then it must be a self-portrait.
Does anyone know more about this ?

Now I see. Thank you for explaining.

I'll have to brood on this for a while.

Yeah, there's probably 1000 different places you could find the golden
ratio or a Fibannochi number on a single plant...

Yes, but you'd need an efficient data structure to find the closest center
to a given sample point quickly. Fortunately, I've done some work in that
field (though in 2D) so I have some ideas on how it might be done.
Such a pattern would solve Gilles' lizard-skin problem, too.

You realize, of course, that there's a relationship between the two.
If F(n) is the n'th Fibonacci number, then
lim F(n)/F(n-1) = phi
n -> oo
(where "oo" should be taken as a low-resolution version of the symbol for
infinity.)

I think the pattern adds to these images. A regular 50*50 grid might
look good, but these 2 images say "Hey! Look at this!"

Yeah, if you take a look at the official Frazetta website
http://www.frazettaartgallery.com/ they mention this self-portrait briefly
in his bio.
