In December, 2012, the Massively Multiplayer Online Game called Glitch (http://en.wikipedia.org/wiki/Glitch_(video_game)) was closed down
Now developer Tiny Speck has released Glitch art assets into the world. More than 10,000 pieces of art and animation from the game are now freely available for anyone to use through Creative Commons. So you can use these art assets in your projects for free :-)
