Open Air is an interactive artwork that allows participants’ voices to transform the sky over Philadelphia. Using this app you may record a voice message and it will be played-back over the Benjamin Franklin Parkway using 24 powerful robotic searchlights that will react, both in brightness and position, to your voice’s frequency and amplitude. Also, if you are on the Parkway during playback, the lights will all point in your direction.

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. For all project details visit www.openairphilly.net
