You don't want Bodypaint. Trust me. It can do everything mc3d says, but is extremly hard to learn. It will take you several months just to get started. You are talking to one who are used to learn a new programming language over the weekend. Imagine yourself tied and blindfolded in a dark room. That is how it feels to get started with Bodypaint. I only learned it because I always persevere like an idiot.
