Finished up our project for Geeks WithOut Bounds (http://gwob.org) at 5am this morning… it’s a game that crisis managers will be able to integrate into their websites and ‘playsource’ the tasks of Translating, Locating and Categorizing text messages from people in need. The gamers get badges posted to facebook, providing as much incentive as Farmville 
The ‘game’ portion isn’t there yet, right now it’s a pretty form that pulls data from the crisis management software (which has an integration with a txt/im api, tropo.com), pushes responses, and tracks the experience for badges. It’s ripe for creative individuals to go hog-wild with it, however…

If anyone is interested in continuing this work, let me know… I had to throw it up onto git, but I hate git, so I probably won’t be pushing any updates.
