The Mp3 Experiment Eight

For our latest mission, over 3,500 people downloaded an MP3 file and pressed play simultaneously. The event began at sunset in two starting points by the Hudson River. The masses converged on Nelson Rockefeller Park as twilight ended and participated in a series of synchronized activities involving flashlights, camera flashes, glow sticks, and masks.
