Lozano-Hemmers installation celebrating free speech runs into NYPD censorship

Rafael Lozano-Hemer is turning the Park Avenue tunnel in New York into a reverberating sound and light installation celebrating free speech. Visitors will find a silver intercom to speak into and their comments will pulse through the tunnel in waves of sound and light. However, the NYPD has voiced concerns about content and has asked the artist to install a time delay so comments can be regulated. Lozano-Hemmer has refused to play ball saying "This is the place for people to express their views...I've never in my life censored a work, and I won't do it."

Rafael Lozano-Hemmer lights up Philadelphia's night sky with an interactive artwork

Open Air is new interactive light experience created by Rafael Lozano-Hemmer "to open up a new public space for Philadelphians to express themselves in." Using a free mobile app developed by Lozano-Hemmer's studio, participants are invited to record and submit messages of up to 30 seconds in shout-outs, poems, songs, rants dedications and proposals. In response 24 powerful robotic searchlights stationed along a half-mile section of Benjamin Franklin Parkway create a dynamic light formation in the sky. The lights respond in brightness and position to the GPS location of participants and the frequency and amplitude of their voice recordings. All participants receive a personalised webpage created automatically with their message and images of the light sculpture that their voice created.
