A little background: I love Rocky Horror Picture Show. In the beginning of the movie, a pair of lips sings the first song in darkness. I wanted to replicate this effect with karaoke lyrics and/or the actual lips, but I had some trouble getting these items to work. Greg Borenstein made an updated version of his face mesh that differentiates between the facial features, and I used this as my base code. I’m still working on this, but this is as far as I got: http://itp.nyu.edu/~ka1019/CompCams/lips.mov
