When I was in college, a friend told me how he and his brother decided to use small tiles, some black, the others white, to make a random-patterned top for a coffee table. It turned out to be extraordinarily difficult. The would start by setting tiles out — randomly — and then see a clear patter or picture. So they'd try a different arrangement and get a different pattern or picture. He said it was really difficult to make a random pattern that *looked* random.
