I think it is a nice idea, but not practical for me. I would have to agree with Wolf359. It would really only take a few minutes to keyframe secondary facial expressions to go with the auto lipsynch generated by mimic, but with the the system you are suggesting it would take at least an hour for me just to set up the animation. Then after I created the animation I would still have to line up the audio track with the animation so that they would match perfectly. Too much work for me, but it would be a great idea if Mimic wasn't around.

I really do think it was a wonderful idea for people who do not want to buy Mimic.
