I'm not really sure exactly how this all went down, but this is awesome. In Trafalgar Square (I'm not sure when) all these people got together and did the coolest thing I've heard of in a while. Inspired by improv everywhere and made a reality by hundreds of volunteers, at exactly 3:30pm on a secret cue, almost everyone in the square froze. The few bewildered tourists didn't know what was happening. For 5 minutes the participants held their positions, and then magically everyone unfroze.
