Inside Out is the project street star JR announced some time ago. It is a meta_portrait of a whole world. Photobooth trucks are travelling the planet, taking pictures of people, printing them big and pasting the posters in the streets. A cool project. Moreover, if you scratch underneath you can see that we are ONE and that we have to take care of our cities (not just the walls, a city is a more complex habitat, made of buildings, persons and the streets _ real and emotional _ that connect them all). Follow them.
