Hope that help a little...

Coming Real Soon Now...

I plan to add documentation to the library code files and create a usable sample
scene using them as an example.  In the mean time, I can create a version of
this scene with additional object types and I can pervert the surface as well.

This sounds far more exciting than simply perturbing the surface!
Perhaps a saucy image_map?
I can't wait to see what "additional object types" you'll use . . .  ;)

Hopefully the sample scene doesn't perturb anyone too much.  :D
