Jane McGonigal has developed this slideshow about using games for city scale collaboration. It’s something I am working on as part of my Bus Meister project (http://www.andynash.com/projects/busmeister/index.html). It looks like we are going to get a small amount of seed funding from the city of Vienna to develop a game and start the social network and best practices wiki database. More later, but McGonigal’s work is extremely interesting and well worth seeing.
