20Q - 20 questions

I'm currently obsessed with 20Q.net! It's an online neural network that guesses your thoughts. Well sort of. Think of a thing, an animal, a metal or a plant for example, and by asking 20 or so questions it will usually have found out what you were thinking about. The really fascinating thing is the questions, they all seem so unimportant when asked but all of a sudden 20q.net has guessed your thing!
