- * As far as I can tell, OpenGL doesn't do shadows. As a result, the
- forward-facing interior walls are drawn bright, not dark. If it was
- casting shadows properly, it wouldn't matter so much that the edges
- don't quite line up, because the lines would be black, and thus not
- visible. But the edges don't match up, and so the bright interior
- faces show through, and that sucks.

- But apparently there are tricky ways around this:

- I think these techniques require GLUT, however, which isn't
- (currently) required by any other xscreensaver hacks.
