Häagen-Dazs has debuted an augmented reality iPhone app called the Concerto Timer. When users launch the app, they point their camera at the lid of any pint of ice cream and they’ll hear a ‘virtual violin concerto’ for two minutes – just the amount of time it takes ice cream to reach ideal consistency for eating. They recorded actual musicians playing instruments with Xbox Kinect, and rendered them into 3D forms. Whether this is successful or just cheeky remains to be seen, but at the least it’s an interesting way to turn an otherwise mundane activity into something fun and engaging.
