OK Go, still not resting on their laurels as pop music's most insanely clever music video-makers, have just unleashed their latest, which was shot in Japan with the help of about a hundred Japanese schoolgirls. Also, they're riding these awesome motorized unicycles, the likes of which we're probably going to be seeing rolling down Valencia any minute now.

This video, for the track "I Won't Let You Down," follows on the June release of the also incredibly elaborate video for "The Writing's On the Wall."
