"You may never have heard of them, but Massimo and Lella Vignelli are an almost daily influence in modern lives, especially if you live in New York. The joyously symbiotic First Couple of modern design is featured in this sprightly, informative doc which may very well change the way city folk see everything around them. An impressive array of professional constituents like Richard Meier, Milton Glaser and Steven Heller weigh in. 'Design Is One' is a cheerful, inspiringly upbeat exploration of the duo’s dauntingly chic yet somehow warmly welcoming world, and the innumerable other worlds they have created."
