Chrome World Wide Maze
I think this is the first time I've been genuinely impressed with a Chrome Experiment.They've recreated Super Monkey Ball entirely inside the browser, with the option of using a device as a controller. Certainly an interesting concept for multiplayer gaming, imagine Chrome running on a Smart TV(Chrome OS TV?) and a couple of friends can hook up their mobiles as controllers, and play some casual party style games like Monkey Ball or Mario Party.
