The 50 Best Inventions of 2009

This year the maker of the world's first digital camera, Fujifilm, introduced a 3-D digital camera: the FinePix Real 3D W1. The 10-megapixel FinePix has two lenses, set about as far apart as human eyes, which snap shots of an object from slightly different angles. Those images are then combined into one, creating the illusion of depth. Its 3-D images can be viewed — without clumsy 3-D glasses — on the camera's back LCD screen or displayed in a special digital photo frame.
