Wacky enough to do the same sort of thing with a cube on a Commodore64... obviously, they were anim files, not Quicktime. "64K?!?! My God! How will you ever fill that up?!?". 8-). Just the knowledge that sneaky is available makes it a little less impressive on a PPC604, though. The old debate between whether you should throw fast hardware or clever software at a problem, I guess... (PS: the correct answer is "both". 8-)).
