NYC Flash Mobs
From Daypop, and not to be missed: Flash mobs take Manhattan. This is so New York.
Of course, we Southern Californians have our own version of this. It takes place every day, on the 405 freeway.
Update: See also this account of the event in question: Mobs rule! And also these additional photos.

This sounds a lot like Critical Mass in SF (and arround the world) except without the bikes…

…of course, the surrealness of it happening in a store where everone pretends to know eachother and then disperses in 10 minutes is pretty cool (allthough i can’t imagine it scaling to 1000 people as easily as Critical Mass)
