In 6 Days to Air, the documentary about the making of South Park there is some great footage of the animators working on the characters in studio on wacom tablets. I couldn't tell what program it was. Does anyone know if it is a proprietary suite or something that can be purchased? I'd like to make my own cartoons, is there a comparable program one could look at for single users is available for mac? It would obviously have to be more beginner oriented.
