GROWING UP IN A FRANK LLOYD WRIGHT HOUSE, Excerpt:
My mother led us over to the trim on the ceiling in the living room. Recessed lights covered the perimeter of the room, housed behind a shelf trimmed with a 4-inch strip of oak. “See this wood? It is cut on the diagonal so your eye doesn’t stop when you follow the path of the trim around the room. It if was cut on the vertical, up and down, your eye would stop, interrupting the flow.”
