is a component of Maya Unlimited from Alias|Wavefront. You can download a free version of Maya Complete at www.aliaswavefront.com.

Maya Live enables an animator to use a video clip as a moving background. The animation camera in the Maya software tracks specific, user-defined points in the movie background, which then enables the computer to define that movie as existing in a 3D space. At that point, the animator is able to, say, replace that neutral blue skullcap you might be wearing in the original movie with an elaborately inscribed helmet, for example.

The animator could just as easily make stars that sparkle and circle your head, as if you were confused. Really, truly impressive software.
