Great idea. Not quite clear if I see a convincing/realistic fat/heavy man option above. That would be a wonderful tool. The idea of young-> old that you are working out is very appealing. Would your program also allow a reasonably realistic series of a PARTICULAR individual growing older, as one might like in making in a story? It would be fantastic if there were a way of making a particular character and then adjusting her/his age. But I'll bet that would be a rather complicated thing to attempt.
