I posted about OK Go‘s recent video Upside Down & Inside Out a few weeks ago, but today I re-read the MetaFilter thread and discovered the Upside Down & Inside Out FAQ and credits for the video. I like their explanation of weightlessness on a parabolic flight, which is better than what one finds in most textbooks.
I also enjoyed OK Go Singer Passes Out During Music Video Shoot. See The Footage on Guff even though the title is a bit over the top. Scroll all the way down for the eight-minute video of the last day of shooting.
