Now we know what students do for fun over at Stanford University. If this video is to be believed, they wave their iPhones around while wearing speakers strapped to their hands. (Actually, the whole production seems kind of like using a weirding module, so maybe they’re onto something.) The speakers amplify the different sounds produced by various iPhone apps to create a glorious symphony, courtesy of the MoPho (Mobile Phone) Orchestra.

Some of the music apps are quite fun–like the one called the “Ocarina” that transforms your iPhone into a 12,000-year-old wind instrument (but with more apps). Check out the video below for a demonstration of both ancient music and modern compositions played on the iPhone, from Stanford’s Center for Computer Research in Music and Acoustics.
