Google AI experiment needs your cruddy doodles

Google unleashed a new group of online artificial-intelligence experiments and one in particular stands out as both an addictive game and a fascinating window on machine learning. Quick, Draw challenges you to create a series of drawings in under 20 seconds apiece. The neural network tries to figure out what you're drawing as you go. It learns from its mistakes and seeks to improve its recognition skills. I'm no great visual artist, but the AI racked up an impressive 5-out-of-6 score on my first round, correctly identifying grass, a helicopter, a penguin, a remote control and scissors.
