The Rubik's Cube is making a comeback. There's a lengthy discussion about "speedcubing" -- trying to solve a cube in the fastest time possible. My favorite quote from the article:

Indeed, a live speedcubing demonstration (there are dozens of videos online) can be almost too dorky to describe -- harking back to junior high and all those negative feelings toward the kids who blew the curve in algebra. A world-class speedcuber's skills are a wonder to behold, if you can suppress the urge to chuck an eraser at his head.

(Via Linkfilter.) If you don't have your own Rubik's cube handy, you can practice with this online version.
