Paul, that's really nice.  I have a grant for this summer (o.k., winter for
you) to enhance my on-line Pre-Calculus class -- I'll use Povray for images
and animations.  I find myself always trying to decide between quick and
pretty.  Personally, I usually opt for pretty (even though I don't always
have a good eye for "pretty"), not just because it's fun, but for
legitimate reasons, like, it increases student interest, and often enhances
understanding.  I haven't been pushing it to the extreme of
"photorealistic," but, seeing what you've done, I might just attempt to
raise the bar on a few of my illustrations.
