Frank Lloyd Wright: Designs for an American Landscape

Architecture is the triumph of Human Imagination over materials, methods, and men, to put man into possession of his own Earth. It is at least the geometric pattern of things, of life, of the human and social world. It is at best that magic framework of reality that we sometimes touch upon when we use the word 'order.' - Frank Lloyd Wright, 1930, 1937 

Here is a link to the U.S. Library of Congress' web page dedicated to the physical exposition "Frank Lloyd Wright: Designs for an American landscape." The expedition opened in November of 1996 and closed in February of 1997.
