A few more ideas...
1. A little more rendering, so the parts look more realistic(not pov-ray
quality, but so it looks great)
2. parts that automatically move(such as a continuosly waving hand on a
mimifig)
Basically, I'm trying to make this like VRML for Ldraw(yes, I know a
converter exists, but it looks so clunky.
