This is pretty cool. The concept is quite simple: a headband with a ring of IR LEDs and a battery. When photographed by a surveillance camera, there's basically a big white dot where the subject's face is!

It just occurred to me: I wonder if the same thing might work for traffic/photo radar cameras... A simple license plate frame...
