Sure, once I clean it up I'll eventually post it in p.b.s-f.

Well, actually it means, "As suspected, David is a god." or, in proper
characters, "$B$d$C$Q$j!"%G%S%C%I$5$s$O?@MM$G$9!#(B"

David,

        That is really cool.  I can't wait for you to
post the source code.  In the mean time, I've tried to
re-create a similar shape.
        The big problem with my version is the facets:
you can see that they are actually two noncoplaner
triangles.  I tried to use a smooth triangle to cover
that but someone I can't get the normals to work.  No
modeler used: this is all pov coding.

So, non-coplanar facets are easy! You'll notice that on mine, a row of
paneling on the outside of the shape eventully works it way around to the
inside. Also, I beilieve strips don't meet themselves after a full trip
around, so it's like a mobius strip.

Sorry for the delay
source will be in p.b.s-f

I actually had not noticed that.  Woops.  Hmm.  That's why you
have seven coils: otherwise the six-sided cross section would not
work.  Aha!  That also means you can only use an odd number of
coils.  So does the mobius-like  twisting somehow cut down
on the amount of curvature on the individual facets?

I learned a lot of math and pov in the progress of attempting
to emulate your picture, so thank you for posting it!

I'm not following. Why do you think I can only use an odd number?

Not entirely sure what you mean... the facets are perfectly flat, except for
the last one (where it must meet up properly with the first), the mobius
twisting is a side effect of them being flat.

No problem :)

With my great mastery of photons that'll only take a month or two :)
