Glitch, a collaborative, web-based, massively multiplayer game developed by Tiny Speck, Inc. (tinyspeck.com) has beenreleased under the Creative Commons CC0 1.0 Universal License. I'm not at all familiar with this game, but it is rare that both source code and all game assets are released into the public domain, which makes this announcement noteworthy. An excerpt from the announcement: 'The entire library of art assets from the game has been made freely available, dedicated to the public domain. Code from the game client is included to help developers work with the assets. All of it can be downloaded and used by anyone, for any purpose. (But: use it for good.)'"
