How fun is this: the folks at the the disposable memory project are leaving disposable cameras around the world for anyone and everyone to find. People are picking them up, snapping a few pics and passing them on, eventually returning home for their stories to be told.
There are - at this moment - 183 cameras in 44 countries. Twelve have returned home, 55 found and passed on. 114 are still missing.
I would love to stumble across one of these, wouldn't you? :)
