This is the only web camera that records three-dimensional videos. Using the same technique as in 3D movies, its two cameras record slightly differing images, which are combined to create an anaglyph--a stereoscopic image. A viewer needs nothing more than 3D cyan/red glasses (five pairs included) to see the three-dimensional image. The camera "hangs" from the top of your monitor with its arms and plugs into your PC running Windows XP, Vista, or Windows 7 using its built-in USB cable (requires USB 2.0). Its two cameras can capture video at 800 x 600 resolution at 15 frames per second, and it can focus in up to 12" away for dramatic 3D images. The camera can also provide picture-in-picture videos (both images are two-dimensional) as well as side-by-side videos. It can also be used as a normal web camera. Includes software and a quick set-up guide. 5" H x 4" W x 2 1/2" D. (3 3/4 oz.)
