Geeks used to be famous for playing musical instruments. In a way, they still do, but the instruments have changed and have become iPhones.

"Once upon a time, orchestras required instruments. Then computers reproduced the sounds of symphonies. Now, band geeks are playing iPhones."

Stanford University's newest ensemble is called MoPhO, short for Mobile Phone Orchestra. Its conductor, Ge Wang, is a veteran of Princeton's Laptop Orchestra (see issue 14.04) and is obsessed with making electronic music as mobile as possible. "The iPhone holds a lot of potential for what kind of music can be made and how it can be made," Wang says.
