The Common Camera Project is a neat experiment started in 2009 by a group of Berkeley students led by Kevin Huynh in which hundreds of disposable cameras are being passed around the world with these simple instructions on the back of each one:
Step 1: Take a picture of something that inspires you.
Step 2: Pass the camera on to someone you trust.
Step 3: If you’re last, mail the camera back to us.
Over 300 are currently in the wild, and they have a special page tracking their progress on a map. The resulting photos will be published to the Common Cam website and possibly in a book or exhibition as well.
