In 2011, street artist JR won the TED prize to use art to affect change in the world with a global art project. Inside Out invites anyone to participate by including their faces in a global mural in which your expression reveals your feelings about your chosen cause. The exact meaning of the project is both ephemeral and in constant flux- and therefore in line with its mission to show the true face of the global community.
Part of the project involves mobile photobooth trucks that take pictures of participants around the streets to be included in murals around the cities they inhabit. I was recently able to take my family to JR's Close-Up show at the Magda-Dansz gallery here in Shanghai, of which the photobooth truck and Inside Out project were a part.
Participating in the project was an amazing experience and gives you the feeling of being connected to something big. To get a sense of what this connection means, have a look at JR's 2011 TED Talk about his wish for the world.
