Sugar-Cube Size Projector Coming to Cell Phones

Researchers at Germany's Fraunhofer Institute for Photonic Microsystems IPMS in Dresden and the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena have invented a projector for giving PowerPoint presentations FROM YOUR CELL PHONE. The projector will use a single mirror and tiny diode lasers. Red and blue lasers are small enough, and as soon as they can figure out how to shrink the green ones, we'll get our phone-projector.
