The People's Clock: A Timepiece Made of People

Kind of reminds me of the "Living Chess" performances they do at ChessFest in London where actors dress up as chess pieces on a large board.

Looks like they recorded people in a time-lapse and then broadcast it as a looped video synced to the current time. Watching the sped-up timelapse is pretty funny because it looks like a clock surrounded by a nest of angry bees.
