I'm working on a way to play the card game Mao online, except that, as Mao is a game that lets you make your own rules, in order to be capable of playing a substantial subset, it'll have to be capable of playing any card game.

(Yes, I've thought about turning this into a startup.)

And that reminds me, I really should be working on that right now, if I'm going to have time to do my college apps...
