Hello, I mis-placed this last night on the binary text news server. I now
realize this is the place to put images!
I wanted to see if anyone could figure out how I made this object
(attached). Evidently, it has been cut open with other objects, but the
texture and the shape are not usually possible. The pigment is a real 3d
pigment.

Two ways, I reckon. One is a parametric in SuperPatch, the other
(simpler) is to create the usual straight log, slice it in parts and
bend it.
Do I win a candy bar?
Ha! I beat you to it! You might want to check out my twister.inc I
recently posted in p.b.utilities, as well as several examples to it in
p.b.images . It does the same effect.

Looks like sphere's placed along a sin/cos path and then carved up.

Looks like iso-surface with an iso-texture, right ?

Bingo! What I wanted to do more than anything else is to make people aware
of the superpatch's ability to make brand-new pigment types from
mathematical functions, using the isosurafce. I found the isosurface to be
a thing which can be learned, even though I had no previous experience
using such math equations. Simple trial and error leads to learning.

Here is the code for all you superpatch users:
camera{location<0,5,-10>look_at<0,0,0>angle 35 rotate y*-45}
light_source{<100,200,-50>rgb 1.2}
sky_sphere{pigment{gradient y color_map{[0 rgb 1][1 rgb<.3 .7 1>]}}}
isosurface{
function sqr(x+sin(z*2))+y^2+.5
bounded_by{box{<-2,-1,-4>,<2,0,4>}}
sign 1
threshold 1
pigment{ function sqr(x+sin(z*2))+y^2+.49
frequency 8 color_map{[0 rgb<.3 .3 .15>][1 rgb<.9 .9 .8>]}}
finish{phong 1}
}
