Random thought for the night: Tetris is NP-complete, and thus difficult for a computer to solve. Tetris is also fairly easy for quite a few humans. Stay with me, here. If you have a convenient algorithm for solving an NP-complete problem, it's trivial (for folks who know how) to convert this algorithm to solve any NP-complete problem. Right?
I have this image of a room full of kids, sitting at terminals, playing Tetris, unaware that the game they're playing is a translation of another NP-complete process entirely. Think of the game room from Ender's game, but they're all actually playing Tetris, never knowing that they're winning a galactic war or whatever.
This is either really cool or really dumb.
