Smule's Ocarina app, which lets you play your iPhone like a flute, has been a surprise hit. And their recent contest has ended, with 10 Ocarina performers each winning a $1,000 prize. You can view videos of the winning performances on Smule's site. One of my favorites is the performance of Oh Shenandoah. Also, there's a neat duet. Smule has now extended the contest until February 13 and will then name 5 more !,000 winners. Unfortunately, one of the performances I liked best didn't win: Tapion's Theme. Also, Totoro's performance.
