Having had some experience building web-based avatar-generators (in the defunct highfiber v6), I have a pretty good idea how much time and effort has to be put into developing these things. This Simpsons avatar builder is a great example: very nice facial-feature controls and a fairly big library of items to choose from.
My only complaint? No way to get a different set of clothes. I want a Sideshow Bob loincloth! :(
