I've never really done any stop motion with a character (only did some tests in school with clay), but it was pretty fun just doing some straight ahead playing around. I still prefer cg in it's infinite preciseness, but it's fun to be able to get away with rougher animation in a 3d format like stop motion. It's also great to actually get to work with your hands and feel the character in your hands.
Next time I think I might use my webcam for a more stable way to shoot this stuff. I could also then be shooting from a higher level. My lack of a tripod kept me at table level with my camera this go.
