Remember a few months ago when we started seeing those promotional videos for the UNI-CUB, a weird mobility device that appeared to be a cross of Segway and a stool?

Critics blasted the personal mobility device as just another thing to make Americans fatter and lazier.

Well, the music group OK Go may have just helped invent a market for the UNI-CUB with an amazing new music video released Monday.

For their latest single, "I Won't Let You Down," the group, who brought you the unforgettable treadmill music video a few years ago, is back and blowing our minds again.

"I Won't Let You Down" features more than 2,000 performers, loads of colorful umbrellas and, of course, the stars ... by which we mean the UNI-CUBs. Honda, maker of the UNI-CUB, helped pay for the music video.

OK Go was on the "Today" show Monday morning to release the video. The group said the video was all one shot, however, parts had to be shot in sections becasue there "just aren't that many UNI-CUBs in existence."
