Love it! Animated would be cool.

Wow!  That rules!  Wow, again.
dang, that's nice.  I'll guess a cells
pattern warped around into an iso-surface,
but how did you get the rounding?

Thank you.

I might do an animation of something similar later when one
of my PCs is running idle for a while.

(The NSSS macros needs about 9 minutes for the subdivision.
And if I save the resulting mesh to an include file after
parsing, then POV-Ray uses 2.5 minutes to read it in again
(2GHz PC). - So an animation would take some time.)

Thank you Florian (and Mick),  I'm flattered =)

But I need to say that I'm not very patient with textures.

Often I do as I did with this texture: Pick one of the
textures that Gilles has made and then modify it.

Yeah, it's one of those models that would be cool to be able to 
translate into the real world.

Though I doubt that is doing to be possible any time soon. :)

I really quite like the second one. (Looks like it should be on the 
cover of a CD full of electronic music... heh.)

Thank you. This shape is made with smooth triangles in a mesh.
There is a short explanation of how I did it in my answer to Arlo
in this thread. (John's NSSS macros take care of the rounding.)

I believe that it should be possible to make the same shape with
an isosurface though.

The mesh for this shape is "closed", so it should actually be possible
to print it out in the "real world" with a 3D printing machine.
Have a look at these pages:

http://www.google.com/search?q=%22rapid+prototyping%22+%223d+printing%22


I even made some POV-Ray macros once that output a mesh in the STL
file format, which is often used for such printing. Here's more about
that format:

http://www.gom.com/pub/specifications/stl/stl-en.pdf
http://www.cs.berkeley.edu/~ug/sif/STL.shtml


It shouldn't be difficult to modify the the NSSS macros so that they
are able to write meshes in STL format too.

But the texture's are another problem...

Yeah, there are lots of techniques now, which is cool... but it's not 
exactly a household machine. :( Do you know of any companies that 
produce single or small quantities of 3D printed objects?

> But the texture's are another problem...

But then you get the joy of hand-painting your object.. :D
