This sounds too cute not to share with you all. Orange County Library System has created a new game to promote gaming in their library:
What has the Orange County Library System been up to lately? We just made our new flash game, Citricon: Library Defender, live! Aliens have stolen the Library’s books, DVDs, and CDs, and we need your help! Play Citricon: Library Defender and help squirt get them back! You can play the game here: http://www.ocls.info/Virtual/Galleries/Events/gaming.asp

Awesome game! Kudos to the OC LS! Could perhaps be made better with a few tweaks to bring in some learning content like names of books and other items? Wish I had programming skills to do this kind of thing…
