I put disposable cameras out into the world (chain them to walls, etc). You take pictures of whatever you want with them. One camera's instructions read: "take a picture if you're feeling happy" and the other camera's instructions read: "take a picture if you're feeling like something else." I add some captions, then scan them onto this website. The world will view them here.
I just put the first "Take A Picture" camera installation in Webster's Bookstore Cafe on Allen Street in State College, PA. To be a part of the first wave of participants, go to Webster's and check it out!
