This past Saturday anyone with a music playing device was invited to The World Financial Center Plaza by the North Cove Yacht Harbor. Potential participants were told to be there by 4pm, to wear a red, blue, yellow, or green t-shirt, to bring a watch with a second hand and a camera if possible, and to download an mp3 from their site.

Sound familiar? It was the fourth Mp3 Experiment organized by Improv Everywhere. Ah, that Charlie Todd never ceases to amuse us. Below is a time lapse video of what the scene looked like.

For on-the-ground footage, go here. In total, 826 people downloaded the same mp3, pressed play at the same time, and, you know, had an experience.
