How to Make a Musical Instrument out of Bananas

By Rebecca J. Rosen

What if your pencil drawings could become your video-game controller? Or, weirder yet, your bananas could become a musical instrument? Such conversions from physical objects to digital interfaces are possible with MaKey MaKey, a kit designed by two MIT Media Lab students, one of whom, Eric Rosenbaum, discusses how it works and what it could lead to in a video from the Aspen Ideas Festival below. We're used to being able to create new things online -- whether it's starting your own website or making your own videos -- and we've all explored building in the offline world, whether just doodles on a page or music from an instrument.
