Under-skin displays
Dermal Display. "In his book Nanomedicine [...] Robert A. Freitas Jr. describes [...] a "programmable dermal display" in which a population of about 3 billion display pixel robots would be permanently implanted a fraction of a mm under the surface of the skin, covering a rectangle 6 cm x 5 cm on the back of the hand. Photons emitted by these pixel bots would produce an image on the surface of the skin. This pixelbot array could be programmed to form any of many thousands of displays."
