A Stop Motion using Warhammer 40k tanks. Made in just under 4 hours at school during our Open-day. Haven't added any sounds yet but this was fun to make.
EdIt: I really have to thank my 'cameraman' on this too. He sat there at the Mac making sure my hands weren't in the way, that I didn't move the pieces too far, making sure it looked right on screen. And most of all, he took the pictures. It wouldn't even be half this long without him (it takes alot of time to keep running around the table just to press the spacebar let alone check to make sure everything is correct).
