The awesome people over at SnapItSeeIt.com have sent three Polaroid 600 cameras out into the wild to be passed from one wonderfully creative person to the next. You shoot 1 pack of Impossible Project film in it and then sent the camera on to the next person.
My personal favorites:
Scott Asano: Love the mixture of organic shapes and strong geometry.
Fabian Carlos: Looks like a great day at the beach.
Matt Mcdaniel: Wonderful, minimal compositions that remind me of what I love about conceptual art.
You can see all of the results here.
