This fall, members of the public can record 30 second messages and see them play out abstractly on the Philadelphia sky. “Open Air”, an “interactive light experience” above the Benjamin Franklin Parkway, aims to use technology to transform the sky over Philadelphia. Artist Rafael Lozano-Hemmer designed the installation on commission by the Association for Public Art.
Every night from September 20 to October 14 the project will make huge light formations, visible from 10 miles away, that are automatically controlled by your voice.
Visit http://www.openairphilly.net/ to record a voice message and listen and rate other entries. The higher rated messages are played back over the using 24 powerful robotic searchlights that react, both in brightness and position, to your voice’s frequency and volume. There’s also an Open Air iPhone app you can download free.
