Is it bigger than a loaf of bread?

OK so here's this neat thing called Twenty Questions. Its creators are calling it "an experiement in artificial intelligence." I'm calling it "a half-interesting way to waste time at work." It's basically a website/game that is designed to guess what you are thinking of based on - say it with me now - twenty questions (or less). Now when I say "designed to guess what you are thinking of", I don't mean that it'll know that you're secretly plotting the murder of the new intern in your office and then planning to stealing his identity and hightailing it to Guadalajara where you'll purchase a tiny blue agave plantation with your savings and make a modest living off selling your harvest to local tequilla manufacturers. What I mean is, you think of an object and you start by establishing whether it is Animal, Vegetable, Mineral, Other or Unknown. From there the program asks you various yes-or-no questions until it eventually guesses the object you're thinking of. Here's where the A.I. part comes in: the program "learns" from the answers you give to its questions and uses your answers to build its database and become "smarter". It guessed that I was thinking of "autumn". Don't you hate it when people "unnecessarily" use quotation marks? Me too. Anyway, try the freakin thing here.

Also, did you notice that cool little leave-a-message thing on the bottom-left of my page? No? Well why don't you scroll down and have a look-see, and then, you know, leave a message mmkay?
