This is a video of a chimpanzee playing pac-man and responding to instructions. Pretty awesome stuff. Reminds me of an excellent episode of Nova I recently watched, regarding the bonobo (which we are almost equally related to). There is some additional information on the
program's website, specifically about the efforts to teach bonobos and the differences they have found compared to teaching chimpanzees. But, while I find bonobos to be more interesting, I couldn't figure out a way to post any of the stuff from Nova's website, so you'll have to watch this Japanese (I think) video of a chimp instead

It's quite interesting nonetheless, and if you find this kind of thing fascinating I recommend checking out the information on the Nova website and seeing if you can catch a rerun of the episode about the bonobo. It's called "The Last Great Ape."
