I am a huge fan of FLW since taking a history of architecture course in college. My computer background is a photo of Fallingwater I took during a visit to the house, if that tells you what I think of his work. There is Kentuck knob close as well as three private homes designed by Wright near Fallingwater. Most of the replies already list some of the most iconic works you can see.
Many of his ideas were "visionary" that is to say "a little crazy" LOL. I'm glad to be living in a house inspired by his designs but made livable, but not actually designed by him.
We almost bought a FLW fixer upper in Maine for 300-400K, I heard it took a million dollars to renovate by the time the owner finished. Dodged that bullet!
