Wright designed a gas station, with a control tower office from which the manager can look down on the gas jockeys.[1] It looks like it belongs in Southern California, but it's in Minnesota.

His Marin Civic Center is nicely integrated with the terrain. Gattica, the movie, was filmed there. Like the gas station, it includes a non-functional pointy tower. Wright went through a pointy object period.[2]

Wright emphasized materials and surface treatments, to complement the plain lines of his buildings. That tended to run up costs. But if you use Wright's lines without the materials, you get brutalism.
