POLAROID POGO

At the Consumer Electronics Show (CES) in early 2008, a Polaroid spinoff called Zink unveiled a miniature, instant photo printer that went on the market in July as the Polaroid PoGo. The printer has hundreds of precisely controllable heating elements, and it uses special two-by-three-inch paper that contains three layers of nanocrystals. When the crystals are heated, they transform into an amorphous glass. Each layer of glass reflects a different color, and the blend of colors is controlled by the duration and temperature of the heating. The printer can connect to a digital camera with a USB cable or to a camera phone over a Bluetooth wireless connection.
