Walking from a friend's apartment at the end of an evening back to my place, I began to see curious things inside the cars on the street, like a tire nestled like a passenger in the front seat. Then I studied the cars themselves, their design details. Finally I stepped physically (and mentally) back a bit to regard the whole scene—a background field with a foreground vehicle. When those two elements clicked—in color, or light, or design—then I knew I was on to something.
