Extremely Compact Color Projector

If you think that your company’s color projector is small, think again. Nippon Signal Co Ltd. recently paraded a SVGA (800 x 600 pixels) compact color projector which measures roughly the size of a standard cigarette box. Despite the diminutive size, it is still able to throw some respectable images and does not compromise on quality. There is not much detail concerning the contrast level and brightness, but it ought to be enough for a presentation in a small, dark room. I wonder what’s the battery life like on something so tiny - must it be powered by an adapter at all times, or is there an internal rechargeable battery?
