Meet James Clewett, Tetris Addict and World Champion


"Confessions of a Tetris Addict" is an unexpectedly engaging YouTube interview with the 1999 Tetris world champion — who grew up into a charming, self-possessed Ph.D. candidate. "I am very, very obsessive, but that helps. It helps with Tetris, and it helps with physics. It helps with everything that I do."
