Bar Mitvah Cartoon Theme

My son is a comic/cartoon fanatic. We will begin planning his bar mitzvah soon and we are looking for any ideas relating to this theme. Especially entertainment ideas. I would like somehting that the kids could somehow interact with. Maybe I would have cartooning instructors teach the kids how to make their own cartoons. Maybe some kind of computer graphics person to help the kids create their own animated scenes. I am just beginning to think about this. I welcome any ideas for entertainment, invitations, party favors, place cards, etc.
