This 3M M2256W Multitouch Display is a 22 inch, 20 finger multi-finger input device. We’re not really sure how 20 fingers works, presumably it can cope with aliens and two people at once. It works with Windows and comes complete with a Tom Cruise mode which increases the volume while looking intense and serious. There’s a video demo on the site too.
The 22-inch 3M Multi-touch Display M2256PW, featuring industry-leading technology from its fast 20-finger multi-touch input to its high-definition, wide viewing-angle LCD, delivers revolutionary performance designed to exceed the requirements of the most demanding professional applications.
