As I mentioned earlier, I wanted to model something like
Escher's "Moebius Strip II" (woodcut from 1963) for my
POVCOMP entry. But I didn't finish my macros early enough,
so I had to abandon my attempt.
Yesterday I sat down and finished the most important
macros and today I debugged them and rendered a scene that
knot.
one of the edges of the band.
Although it is not the scene I planned, I find the shape
in it interesting.

Impressive!
The question from many fans: "Master, how did you do it?" ;-)

I'm allways admirative when I see your images. You're, for me, the
torus-master ;-)

Amazing! It's a mesh, isn't it?

You do know similar things were also drawn by Escher (1965), don't you?

Hehe... The main ingredients are my NURBS macros, my Frenet
Frame macros and the "New Surface Subdivision Suite" by John
VanSickle.
I can try to explain more later today.

I've been very fascinated by the shape and the topology of
tori all the time since I started to try to model smooth
and complex shapes in POV-Ray.

Yes Florian, it's a mesh.
I think that this shape can also be made as an isosurface,
but I don't have enough computing power for that yet.
