For those of us that are not musically inclined whatsoever, watching someone who is truly a master at playing an instrument may as well be magic or voodoo.
Yet another example of the continuous forward march of technology! Jay Silver and Eric Rosenbaum, two final-year PhD students at the MIT Media Lab, have created a way for you to use ANYTHING to control your computer. All it takes in their unique USB interface, some alligator clips, and your control of choice. Even bananas. Amazing!
