Ryan Stewart has a great article on a cool new Flex application called Small Worlds. Its a massively multiplayer online game built with Flex. Ryan describes browsing popular websites and being able to share that experience with your friends - watching YouTube with others (one person controls the channel), picture frames that you can fill with Flickr photos etc... Ryan's got a few screenshots of the game as well, along with instructions on how to get an invite to the beta if you're interested. A good read for a Friday afternoon.
