Lost Digicam, or ARG Launch?
This happened before couple years ago. Someone finds a digital camera and posts some of the pictures from the memory card online in an attempt to find the rightful owner, in this case using a Flickr account. Even though I'm pretty sure this is the real deal, if not the smartest/nicest thing in the world to do, I can't help but think of one thing:
This'd be a GREAT way to launch an ARG.
