I skimmed the videos, and the guy knows his stuff. He's got lots of great ideas.

Yeah, I've thought about doing that but I will need to change the structure a
bit, since right now it just uses rand(), which doesn't depend on knowing the

Doing this with functions (which would permit the use of isosurfaces) might
