A team at the Fraunhofer Institute in Germany has developed this sugar-cube sized digital video projector capable of displaying video/images at traditional sizes. This projector uses a single mirror to display the footage. There is a limited color range because it can only work with red and blue lasers—green lasers are too freakin' big. This laser-based projector could have some useful by allowing more mobile applications and maybe someday be integrated into PDAs or smartphones. Thanks, David
