Gotta love a city that surprises you. Taking its typical elements and reconstructing them in new, fun and socially aware ways has been the weapon of choice of many urban interventionists who managed to inject a dose of playfulness and provocation in the urban scenery. Some of them have done a great job in making a point on social and political issues and serve as an inspiration to citizens to participate in reshaping their environment. And do urbanism themselves. People meet in architecture.
