Try to see, a city as a brain, with the people beeing neurons, containing potential ideas. For a city the most interesting thing to happen, is new connections between the people, in two forms. Personal Connection (very important to realize allready existing new ideas) and contact of a person with new things/ideas. A city could further the interpersonal conntact, by creating partys, festivals or a sort of (non-relationship) speed-dating. But how can a city further the contact of persons with new ideas? What if the person in need of new ideas, heavily resists having contact with them?
