Remember those old toys? Youd turn them upside down and theyd make a mooing sound. Flip them again, another moo. Whats old is new again. Turn your iPhone into an entertaining sound device that moos whenever you flip it from back to front or front to back. It wont build world peace or create unlimited renewable energy but it may amuse your three-year-old for several minutes. Small scale victories can be just as sweet. (Works on iPod touch but requires an external speaker)
Tips: Turn your sound ON. (Muted iPhones do not moo). Turn the iPhone glass down. And then glass up. Mooooo.
