OK GO! Most complicated music video ever?

Ad/moustrap inspired music video from the guys who brought us the treadmill music video.

The video shows an intricate two-storey Rube Goldberg machine in a Los Angeles warehouse that one bandmember starts off by pushing a red truck into a pile of dominoes. It ends with cannon shooting out paint on to the Chicago group. The clip, which is just under four minutes long, is filmed in one long take.
