Once in a while there comes along an idea thats so bizzarre and yet surprisingly useful, Chirp is one of them.  Anything you wish to share is converted into a sound byte that you chirp across to phones and people around you. Did you just chirp your party pic? Something like a hyperlocalized twitter on sound waves.
