Day 93. I've played with 123D Catch and 123D Creature before, but this was made using 123D Sculpt. Basically you start with a lump of "virtual plasticine" and then push it, pull it, extrude it, sharpen it, etc. This weird looking head started as a sphere, but was slowly modelled into this shape, then painted and patterned.
I've been really very impressed with these 123D apps from AutoDesk. I probably need to spend a bit more time with them so that what I make doesn't look quite so bizarre, but I think they could do some very cool things.
