A bit off topic but I was downtown at the ice carving competition this weekend and thought they were incredible. Two guys who I watched for a while were carving Kermit the Frog playing a banjo which they said was the hardest design they've ever done in competition. I got to take a look at their drawings which consisted of a pretty basic, overall sketch of the sculpture as well as scaled sketches of each individual piece. This technique seems like it could come in handy when doing 3D computer animation. Breaking a character or object down into simple shapes and sketching those beforehand would likely make the animation process go much quicker than looking at it in a "big picture" type way. For those of you who missed out on the action, here's an ice carving video!
