Among the things intrinsic to human existence is the totality of all we have built. Cities are the most complex formation of human society. They are the most beautiful and the ugliest, the best and the worst ever invented by humans. They are much more than a collection of lots, buildings, streets, and squares, and more than the most homogenously designed public space. As reflections of their inventors, buildings and cities have to consistently offer and do more. We find ourselves in the midst of a monsoon of polymorphic demands and specific knowledge. And we sense how - in an initial moment without order - sometimes one thing blends or collides with another. Some call this Interference (Interferenz). From this increased experience and knowledge of interference we have coined a different, new concept: Superference (Superferenz).
