Some trivia about Frank Lloyd Wright:
He was a creative genius, but a lousy engineer. He often sacrificed durability for style and flair. His roofs leaked, the Falling Water house was structually unsound and it is a tragedy it was not built to last longer. He was also very short, and often built with low ceilings and low doorways, giving his structures a cramped feeling.
Nonetheless, the way he integrated nature into his designs was truly inspirational.
A closer way to see his work is to go to Talisman West (sp?), just east of Scottsdale, where he spent his last decades designing and working (with unpaid volunteers). Great museum with tours.
