Students build 3D computer interface using copper, felt, and lots of moxie

Always on the lookout for bigger and better ways to faux-scratch a record with your PC, these students at Northeastern University have developed a human-computer interface that utilizes copper pads and our beloved theory of electrostatics. This little devil is able to track the position of a user's hand in three dimensions, without attaching markers to the body or requiring the user to hold some sort of controller. We can think of a couple theremin players that would love to get their hands on one of these things (Mike Love, we're looking at you). But don't take out word for it -- peep the video below to groove along with these dudes as they literally rock the (virtual) bells, play some organ, and even do a little fingerpainting.
