Mirrorspace

When you've exhausted all the functional uses for mirrors (you know, preening, gazing in endless adoration at your pristine visage) you can start having a bit of fun. MirrorSpace
(which is actually several mirrors) uses a USB camera to capture the person in front and superimpose the video onto all the mirrors, which we're sure would be a somewhat creepy experience. The best part is, the mirrors all have motion sensors so that they only do their little superimposition thingy when there are actually people in front of them.
