Speaking of Pilobolus, OK Go's latest video is a collaboration between the band and the dance troupe for OK Go's new song "All Is Not Lost." It takes just a little while to figure out what's going on, and then it becomes increasingly hypnotic. You and your kids can even play with an interactive version of the video.
Also, I'm thinking of just renaming these "Monday Morning Smile" videos for OK Go since I seem to use them a lot for this purpose.
