Play 20 Questions against a Computer

http://www.20q.net/

20Q is an object, a website, a company, and a phenomenon. It first gained popularity as an online game (20Q.net) where users log onto our website and play against an artificial intelligence foe. Players think of an animal, vegetable, mineral, or other item and the computer guesses what the player is thinking in twenty questions. And the more people play, the more the game “learns.” (20Q.net) gets 50,000,000 impressions a month and played its 10,000,000th game in February 2005!). 20Q is now played around the world.
