Hey,

A polar zonohedron without faces, but with cylinders on its edges and
spheres on its vertices, is centered in a spherical room with an ocean or
something as its floor. A light is within the zonohedra, casting shadows
upon the walls. Media was used.

Way cool!  And while you're here, I've got a request:  How about some of
your other polar zonohedra from:

http://www.mathematica-journal.com/issue/v6i2/graphics/towle.pdf

done on POVRay?

(Or I suppose I could read your paper closer and try it myself.  Anyway,
great stuff!)

Hey Dave,

I hope this doesn't violate some protocol, but attached polarzonohedra.zip
should expand to a folder with two files in it.

PZ.pov calls PZ.inc.

PZ.pov allows one to construct the general polar zonohedron, and display
faces alone, cylinders and spheres on edges and vertices, or all at once.
It's a little awkward and I think I made a macro once to do the same thing.
But I forget. I'm fifty-seven after all.

I hope it works.

Hey sorry the previously sent polarzonohedra.zip was incomplete, missing
CYLLO.inc, here is the complete package.

Thanks!  This is better yet!  (I think the usual protocol is to post it in
PBSF --the "scene files" category, but since this one is already cleared
for binaries, it should be ok)
