In their new video, "All Is Not Lost," OK Go teams up with avant garde dance company Pilobolus to don toothpaste green spandex and dance through a kaleidoscopic choreography of HTML 5 browser windows. It's a little as if a synchronized swim team washed up on the fourth wall of the Internet and decided to perform anyway. For the full interactive experience, skip the YouTube video and go to www.allisnotlo.st, which is powered by Chrome and Google Japan. Director Trish Sie and lead singer Damian Kulash elaborate on the inspiration for the video in the behind the scenes.

OK Go's career is a wonderful little case study in how Web video has evolved since they blew up YouTube with their lo-fi, homemade "Here It Goes Again," in 2007.

Since then they've experimented a range of YouTube-friendly ideas, including stop motion, psychedelic visual effects, and lots of dogs, with a keen sensibility for all things viral. How many times have you watched the Rube Goldberg Machine they put together for This Too Shall Pass"?
