Here are some cool videos I found during the week. The first one is a racing game which consists of a classic arcade racing unit, an RC car and a cardboard track. Players use the arcade box to drive the RC car around the cardboard track. Pretty cool!

This second video is a nice demo of a DJ application being used on a transparent glass multitouch screen. The bright interface looks awesome on the transparent screen!

The third video is of a webcam piano, which tracks hand movements and positions via webcam to create music.
