Turn your footsteps into sound as you stroll the High Line. The Gaits: A High Line Soundwalk [2] is a free musical event at 3:30 PM on Friday, December 21.

To join the fun, download a free iPhone application that uses the phone’s accelerometer to turn footsteps into twinkling metallic sounds, electric guitar chords, water splashes, car horns, and applause. Bring your own portable speakers or be one of the first 50 people to arrive and get the chance to borrow a free, wearable speaker.
