Watch a Computer Think

True, this is only a very rudimentary level of "thinking", but by drawing the moves being considered by a chess-playing algorithm one ends up with a fairly eye-pleasing result. Give it a try here [Java application courtesy of Martin Wattenberg], or you could always go try it out in person at the MoMA. The further along one gets into a game, the longer the computer has to consider its move options, which results in more "think traces".
