"Open Air" by Rafael Lozano-Hemmer, Free Event!

“It is a piece about making the air an open platform for participation, like a free, open space for expression using electronic technologies and powerful lights that take over the sky over Philly, a city with a tradition of free speech.”
Rafael Lozano-Hemmer, creator of Open Air
