Lebow, Arthur (6 April 2008). "The Contextualizer". The New York Times. p. 4; excerpt, "...a skyscraper that Nouvel (adapting a term from the artist Brâncuși) called the "tour sans fins," or endless tower. Conceived as a kind of minaret alongside the squat, monumental Grande Arche de La Défense, the endless tower has taken on some of the mystique of Mies van der Rohe's unbuilt Friedrichstrasse glass skyscraper of 1921. To obscure its lower end, the tower was designed to sit within a crater. Its facade, appearing to vanish in the sky, changed as it rose, from charcoal-colored granite to paler stone, then to aluminum and finally to glass that became increasingly reflective, all to enhance the illusion of dematerialization.".
