Working on an general game playing artificial intelligence. Nothing grand, I just have a few ideas I'd like to test in real life. It can theoretically play any game, but it's interesting to see if it's actually feasible, since it's turning out to be quite a resource hog.
I guess my explanation sounded more awesome than it actually is - general game playing has been around for a while now (see for example games.stanford.edu and the wikipedia article on general game playing), mine's a stab at it with some homegrown techniques, largely out of personal interest. As I said, I have no idea if my techniques are feasible or actually work yet, but if they do (and I have the time), the general game playing competition at the 2010 AAAI conference isn't out of the question.
