..maybe you need to get a little more creative. Like these people:
Those are real apps that those students are playing – they really do turn your iPhone into a woodwind instrument called the Ocarina.
The interesting thing is that there is also and iPhone app that turns the iPhone into a guitar. Guess the guitar dude is a PC…
Another interesting feature of this particular Ocarina app is that it is globally connected – click a few buttons and you can listen to different people around the world playing their app – live. The iPhone is just crazy cool that way….
[for more information on this particular app, see the recent David Pogue NY Times post on it.]
