The NY Times has an article on a new technique for capturing human facial expresions; "[the] system requires actors to cover their faces and clothes with makeup containing phosphorescent powder [which glows in the dark]... lit by rapidly flashing fluorescent lights, and the cameras capture light from the glowing powder during intervals of darkness that are too short for humans to perceive."
Here's an image describing the process and a link to a Quicktime movie showing how it works.
