It looks like magic, but it’s just technology. For a casual weekend hack, developer Adam Somers used a Leap Motion USB motion sensor device to turn his computer into a musical instrument. By adjusting settings in the AirHarp app and waving his fingers around like a wizard casting a hex, Somers was able to recreate the sound of a harp, playing in different keys, melodies and timbres. Watch the video to see and hear what we’re talking about.
