As one of the world’s most celebrated architects, Frank Lloyd Wright didn’t have to do windows. But he did them anyway. A just-opened exhibit at the American Craft Museum in New York sheds new light on this mostly unexplored aspect of Wright’s oeuvre. Drawn from private collections across the country, Light Screens: The Leaded Glass of Frank Lloyd Wright features 50 examples of Wright’s radical reinterpretation of the window, using uniquely arranged ornamental glass. “Light Screens” runs through September 2.
