I don't think anything written up for POV so far does something with the uv
kind of vectors such as prism uses. Checking out vrotate for that here got
me nowhere even though I tried to use the dot operator in an attempt to
limit the usual 3 float vectors to two floats but POV will not allow it into
the prism.

I had a feeling you knew a prism wasn't going to do a dodecahedron but I
didn't catch on about the dodecagon name and jumped ahead that you were
confused about the prism. My fault, sorry.

If anyone tells of a way to work with the uv vector, as described above, I'm
all ears too.
