A report from last night's Grand Central Mob: "MOB 3 was ended with about 300-400 (seemed like) people wrapped around the balcony overlooking the lobby in the Grand Hyatt (42nd St.). They were even odder than the peacock-looking little dancers at a convention on the next floor up, especially when, at 7:12 p.m., they all started clapping. It commanded the attention of a everyone who had, until then, successfully glanced at and ignored the huge gathering of people. Exactly 15 seconds after the clapping started, it ended. And everyone left."
