I guess this will be the future of teaching ;D

Wow... that's a cool display.. and they used 4 macs to do it ;)



"This video demonstrates a scalable, 3D multi-touch input system for high-resolution, wall-sized displays. An Interaction Space is created in front of the display wall using eight commodity web cameras connected to four Mac minis. The system can determine the 3D location of arbitrary objects in front of a display wall, and use that information to enable interaction with various applications, including a visualization of genomic microarray data. The system can be scaled to support both narrow and wide display walls by changing the number of cameras used to triangulate objects. This work was presented at the IEEE Symposium on 3D User Interfaces"
