You mean, the camera can't move?  Ooh.... :o(  Anyway you've demonstrated
something that has increased my interest in Povman, and you've done much
better smoke than I've ever seen in Pov.. If you'd explain just the basic
idea, so I can learn how to do it with media eventually ...or would it be
great to use glows? (if Pov3.5 had them...)  Negative glows or glows that
aren't fully transparant..
