City21arises from a worldwide learning journey that was transmuted into cinematic composition illuminating some of the key perspectives and initiatives that are reshaping the ethos of the 21st century city. The underlying quest of the writers is to reframe the conventional and uninspiring visions of the urban future with an unprecedented combination of fresh, invigorating, sustainable, economically viable, and life-enhancing concepts. Some of the themes explored in the book, in an effort to loosen the geometric and economic grip on the urban imagination, are: The Sacred Origins of the City-city plans through time The City as Memory Theater-David Mayernik’s timeless cities: useful knowledge transmitted through the generations Regenerative Design-nature and architecture: the transformation of the Biosphere2 Project into eco-village design The Creative Green City-The Lighthouse Project in Glasgow Findhorn-the art of creating eco-villages Magical Architecture-the underground city of Damanhur, Italy,/li> The Utopian Imagination-poetry and architecture: The Open City Project in Ritoque, Chile Stewart Brand-the long now perspective
