It's too bad - I kept thinking about Eliezer's old post about 'what would ordinary things like sight be like if they were RPG powers/abilities', and it seems to me like a cool concept to try out would be a game where you can literally see the causal decision graphs governing the actions of characters. Perhaps another power could be snipping branches or modifying weights to manipulate characters into doing your bidding or simply getting out of the way. (One could start off trapped in a jail cell... :)

But I've tried a couple ways to view the PDF and I can't seem to see the screenshot of the GUI! Now that's annoying.
