JR: One year of turning the world inside out

Street artist JR made a wish in 2011: Join me in a worldwide photo project to show the world its true face. Now, a year after his TED Prize wish, he shows how giant posters of human faces, pasted in public, are connecting communities, making change, and turning the world inside out.
