Young French photographer/activist/artist, JR, (he goes by his initials), has made the urban world his own outdoor photo gallery. He’s posted his billboard-size photographs — usually portraits of people who live in the area where he displays the photos — on the sides of buildings, on rooftops, wrapped around whole train cars, on the houses that cover a ghetto slum hillside, and even on the wall that divides Israel from Palestine. His work is at once compassionate and provocative. stevia . He won the $100,000 TED prize in 2011, and here is his funny yet passionate speech about how he tries to use art to change the world. Inspiring!
