Abstract :
Not long ago, a kitchen mishap at a Palm Desert, Calif., dinner party caused an hour-long delay between the appetizer and the entrée. Conversation began to lag. Then folks began pulling out their iPhones¿not to check their e-mail but to play Ocarina, a US $1 iPhone app that lets users blow into the phone¿s microphone while pressing on virtual keys to mimic an ocarina, an ancient flutelike instrument.
