Coming Soon: Digital Cameras with Built-In Printers

A startup called Zink and the venerable Polaroid are working on a digital version of the Poloroid camera -- a digital camera with a built-in printer. They're not actually building the camera, but developing technology that miniturizes printers small enough to fit in digital cameras. The secret is that, instead of ink, the PAPER ITSELF is capable of turning any color, and the printer heads simply tell each "pixel" on the paper what color to turn.
