I'm going to try this. Just haven't had a chance yet. A fixed version
would be really nice, but I don't have the code know-how to do it (well, I
don't know the POV code. I could write something, I'm sure.

Might work in this scene, since the detail is small, but I like the smooth
feel of the sphere splines in detail, which is really slow, because of where
it's located.
