Over at the website for The New York Times, they have added a rock-paper-scissors game where you play against a computer, which is getting better and better at predicting what your next move will be.
Computers mimic human reasoning by building on simple rules and statistical averages. Test your strategy against the computer in this rock-paper-scissors game illustrating basic artificial intelligence. Choose from two different modes: novice, where the computer learns to play from scratch, and veteran, where the computer pits over 200,000 rounds of previous experience against you.
