A wall of tiny squares of wood controlled by a camera which when you move tell the squares to tilt reflect the light in different ways, acting like a mirror but with no reflective surfaces. Pointless you say but fucking mint!

Pretty wierd really, uses the same pricipal as a screen and isn't really any sort of mirror. No different really to looking into my webcam.

Yeah its pretty much exactly the same as webcam and a PC screen except it doesnt use any light emitting parts and makes alot more noise

aaarrggghhhhh, no 'r' in the title

lol didn't notice it
