Do you have 835 servo motors sitting around? Why not build your own binary wood-pixel-display-device?

Using the same basic concept as a DMD (Digital Micromirror Device) — the heart of all DLP projection technology — an artist created this wooden mirror. It features 835 wood “pixels” which are controlled by servo motors. Each pixel or wood chip can flip 30 degrees down, and 30 degrees up. A series of spot lights shining on the mirror provides lighting so shadows form when the pixels are “off”. The result is quite fascinating.

A small camera mounted in the middle of the display takes a black and white image of whoever (or whatever) is standing in front of the mirror. A bit of image processing later, and the mirror displays what it sees.
