short-throw projectors: 3M's DMS800. The 0.7-inch DLP projector mounts to the wall yet throws a 1,280 x 1,024 image with a 1,300:1 contrast in sizes ranging from 50 to 85 inches thanks to that long, telescoping neck which can extend up to 4.2-feet. Inputs are available for DVI-I, D-Sub 15 RGB, component, composite and S-Video sources. You can even combine the built-in Ethernet with an optional, external sensor and you've got yourself a digital white board to share on the network. The entire kit will set you back ¥715,000 (about $6,292) as of today in Japan. Still confused? Click through for a sample installation.
