Ocarina transforms the iPhone into an ancient flute-like instrument that responds to your breath, touch, and movements. Created in 2008, it was one of the very first mobile/social musical instruments; its globe visualizes where people are playing Ocarina and even lets users listen in on each other. It went on to be one of Apple's Hall of Fame apps and currently has more than 10 millions of users, who have since 2008 expended 2 billion breathes blowing into their iPhones (see map below) and have listened to each other 47 millions times in the globe! The vision was and remains to bring the joy of music-making to as many people as possible, and to connect the world more through music (with a little help from technology).
