Architect Carlo Ratti describes this proposed mile-high park (nearly twice as tall as the tallest building in the world), which he designed with German engineer Schlaich Bergermann Partner and British design studio Atmos, thusly: "Imagine you take New York's Central Park, turn it vertical, roll it and twirl it." That is such a delightful quote, because it makes it all sound so simply. First you take Central Park. Then you turn it vertical. Then you twirl it. Bing, bang, boom. Anyway, we hope we at least get to see some more renderings of this thing.
