Yesterday brain controlled avatars, today something a little less surreal (and perhaps a little less transformative) in the form of Fix8, which connects Web cam inputs to avatar facial expressions.

The platform isn’t Second Life ready – but hints at the promise of being able to connect user inputs far beyond the mouse and simple HUD-based animations to actually link real facial expressions to those of your avatar.

Which brings up an interesting question for those who are using virtual worlds immersively – do you really want people to know what your face is saying “behind the mask”?
