Here's an interesting idea from Jane McGonigal (Berkeley) and Ken Anderson (Intel). It's called place storming :
Place Storming is context-driven and play-based, combining real world environments with the immersive and performative aspects of gaming. Place Storming combines elements of street games, improvisational theater and brainstorming to enable participants to get out and get physical, in order to find real everyday contexts for technology innovation. Place Storming participants break into teams, take on roles, visit a series of situated places in targeted environments, and use props to accomplish site-specific missions. In completing their missions, Place Stormers become active, playful performers engaged in first imagining and then enacting technological innovations in context.The key word in this is: context. Instead of brainstorming in a corporate office on a whiteboard (with beanbag chairs), the experts/amateurs actually engage with a real world environment (i.e. a specific town) and play an open ended game that forces them to apply the technologies at their disposal to solve real problems. Nice.
What's more interesting to me than corporate brainstorming, is to use it as a way to add resilience to a community. Essentially, every local environment is unique (geography, people, etc.). The technologies and the methods/processes (particularly if they are software based and can be easily tweaked/modified as needed) available to add resilience (self sufficiency) are myriad. A large number of players (both virtual visitors and real inhabitants) interacting with each other and with an unique local environment, to figure out how to make it resilient could be fun and very innovative.
