Nikon Coolpix S1000PJ

The micro-projector has found its niche. The Nikon S1000pj is the first camera with one built in, so you can instantly share your shots and videos with the whole room. The same size as an ordinary point-and-shoot, it uses an imaging chip similar to those in tabletop projectors, plus a low-power LED that bounces light off the chip. The resulting images shine through an extra lens on the front cover, splashing 40-inch murals on the wall.
