An Intelligent Game

Every now and again as a programmer you come across some bit of code that excites you. In this case it's a simple 20 questions game. Now, I'm sure the code is fairly simple. People are characterized with qualities and it asks questions to optimally limit the remaining possibilities. But I tried playing the game about 10 times and it was dead on each time, even when trying to think of people it would likely fail on. I thought it was impressive to have such an extensive list of people that it's been trained for. And every time it's asked something it becomes smarter and better able to determine your person.
