Radiohead have announced the winners of their long-running Aniboom animation contest. Initially, the contest was only supposed to have one winning video, selected by Radiohead from a pool of five viewer-voted finalists. But we all know Radiohead doesn't like playing by the rules, so instead of choosing one video, the band picked four grand prize winners because of "the high caliber and creative visions of the submissions." The winning filmmaker was to receive $10,000 to make a full-length animated video. With four grand prize winners, Radiohead will fork over the additional $30,000 in prize money so that al four filmmakers can make full-length vids, which Radiohead may use in promoting In Rainbows. Among the champs was Clement Picon's chiaroscuro landscape for "Reckoner," which was our personal favorite from the onset and can be seen in the video above. Also getting $10k of Thom Yorke's money is Kota Totori's "15 Step," Tobias Stretch's stop-motion mastery for "Weird Fishes/Arpeggi" and Wolfgang Jaiser and Claus Winter's "Videotape."
