Inspired by the co-creative principles of open source platforms, Mural Arts Philadelphia's Open Source was a month-long, citywide celebration of innovation. A response to major public art events like Miami's Wynwood Walls, Prospect New Orleans, Germany's documenta, and the myriad street festivals injecting creative energy into cities around the globe, it advanced worldwide recognition of Philadelphia as a culturally innovative and global city. Open Source encouraged artists to engage in community-centered explorations, addressing a variety of topics, including immigration, recycling, mass incarceration, the environment, community reinvestment, and displacementall of which inform Mural Arts' long-term artistic and social practice. Features work by Ernel Martinez & Keir Johnston, Odili Donald Odita, Shepard Fairey, Momo, SWOON, Jennie Shanker, JR, Sam Durant, Michelle Angela Ortiz, Jonathan Monk, Heeseop Yoon, Shinique Smith and The Dufala Brothers.
