Who knew Seth knew how to play the harp?
This $600 gadget is a laser harp of sorts. Popular Mechanics has a video of it in action. As the video shows—why can’t I embed it?—every time you break a laser beam, the software plays back an audio sample from one of several different genres, like classical, metal and jazz. Or, if you have any musical talent to speak of, you can program your own sounds effects.
