For my entertainment today, I made 3D avatars of myself (and my many sides) at Meez 3D Avatars. It "only" took a couple hours (and I made 5). These are all animated, but some I chose to only show a still picture because I didn't think the animation added much (particularly the abbreviated animation they do when you have to export it -- the motorcycle had a whole segment doing a wheelie that doesn't show up in the exported animation).
Motorcycle Meez (obviously, I couldn't resist this!):
Diving Meez (They had a "diving" animation, but the swimmer was moving around WAY too much. Diving is about being efficient with your motion and air.):
Swinging Meez (I love this one. The long animation is more fun, twirling around and such.):
Warm & Toasty Meez (I should be longing on the couch reading, but that animation had too much movement as well. I figure this shows me chatting with the viewer.):
Meez allows for five variations, and I am undecided on the fifth and final one. I've tried an office one (but I tend to go for the grouchy looking animations for that) and a hula one and a dressy one, but I think I'll leave it open ended for now.
