Curvy new skyscraper reflects river and rising design ambition

Chicago is a big dot on the architectural map because of its pre-eminent role in the invention of the office skyscraper, a development that transformed the skylines of cities worldwide. But thanks to the Great Recession, it's been seven years since a major downtown office building opened here. Now we have a new one, and its exuberant curves take full advantage of its prominent riverfront site.
