The Top 10 Everything of 2008

4. Ocarina

Some genius figured out how to use the microphone on the iPhone as an air-flow sensor — now we've got a virtual ocarina, albeit not potato-shaped. Hold the phone up to your lips and blow; four "holes" appear on your touch screen allowing you to play almost any scale (which you select under Settings). Share your tunes with other Ocarina players around the world, or just set the app to listen to their masterworks. (The Ocarina app costs $0.99.)
