The band's creative videos have made use of treadmills, dominoes and optical illusions. In its latest, "I Won't Let You Go," the foursome takes to the road -- and the sky -- thanks to camera-toting drones and some Segway-like Honda vehicles called UNI-CUBs.

The video is nearing 3 million views on YouTube.

Part of the idea came from a visit to Tokyo's Robot Restaurant, kind of a Medieval Times with robots. ("Girls in bikinis battle enormous Transformer-style robots, helped by Daft Punk-style storm troopers on Tron motorcycles," went the description of a TripAdvisor reviewer.)

It was the best hour of my life," OK Go's Tim Nordwind told Billboard.

The band worked with Japanese director Morihiro Harano to design the 5-minute-plus clip, which begins with the group on UNI-CUBs doing some leg moves and then rises high over a building lot while the band joined by several -- and then dozens -- of umbrella-toting Japanese schoolgirls. (A choreographer named Airman handled the moves; Honda supplied the UNI-CUBs and some backing.)

Eventually the proceedings moved to a warehouse for the conclusion, a colorful display -- like a stadium flip-card maneuver -- that includes pictures of the band members and a "ribbon" showing the title of the song.

The last part took more than 50 tries and was shot at half-speed and then speeded up, the band members told Billboard. By this point, the drone camera was a half-mile up.

It's all part of a philosophy that tries to entertain as much as awe, OK Go's Damian Kulash told CNN in 2010.

"We make cool stuff," he said. "We just think they're fun."
