My pal Christopher Moonlight has linked me to Maniac World, which has this video:
Frozen in Grand Central Station

This is a prank on a "grand" scale. Over 200 people gathered at Grand Central Station in New York to pull off a 'frozen in place' act. The onlooking travelers who weren't part of the act were mystified as to what was going on.

I can't see a date on the above, but the Frozen at Trafalgar Square is a new attempt at the same effect in London. Some great other stuff here too including Huge tree vs. Little truck, Bird vs. Cat's tail, and Black wasp vs. Aphid
