Inside Out Project

The Inside Out Project is a global participatory art project that gives everyone the opportunity to share their portrait and express what they stand for. It is a global platform for people to share their untold stories and transform messages of personal identity into works of public art. It was launched in 2011 by world-renowned artist JR. Since then, over 300,000 people have participated in 138 countries.
