bickr, Flickr based photo game
Some students at the Interactive Telecommunications program at New York University made a photo game based off of flickr.com called bickr. bickr uses image-based games to raise group effects where participants share physical spaces and compete with each other and against teams in other physical locations. Photos of the first bickr photo battle station can be found on this flickr group pool, they even have a working bickr photo battle station now.
