This is "uploaded" by the group itself, Radiohead, so I guess it's okay to post here.

http://www.youtube.com/watch?v=cfOa1a8hYP8According to Maria Kochetkova's and Wayne McGregor's (Resident Choreographer of The Royal Ballet, etc., etc.) sites, Wayne McGregor choreographed this dance for the lead singer of Radiohead, Thom Yorke.

"An amazing dance, by the way. At first I thought it weird,
but you can actually read the song by it, and it makes sense."
(from a site that posts song lyrics (copyrights?), so you'll have to take my word for it)
Maria Kochetkova seems to zero in on these things and I give her credit as a 'classical' dancer searching for expanded meaning as she shows in her participation in the "Reflections" project.
