In a well-lit room, the PicoP is bright enough to display images up to about 8 by 10 inches. In the dark, it can fill a 100-inch screen. Yet the projector itself is about the size of a stack of three camera memory cards (0.26 by 0.79 by 1.57 inches). At first, it will be bundled with a battery inside an iPod-size device, currently called the SHOW, that several companies plan to sell before the end of the year. By next year, Microvision expects the projector to be built directly into phones, the way cameras are today.
