It would be nice if we could do a little more to make our avatars look like ourselves. There's a nice bit of code that comes on a Nintendo Wii where you can create an avatar that looks remarkably like you, given the rather poor graphics of a Wii. You can select a head shape, hair style, skin, hair, and eye color, glasses, face fur, body shapes, height, etcetera, about 50 or so variables. It can't be especially complicated if a Wii can handle it.
Or, of course, for some of us we would like the avatars to look less like ourselves ;)
