From Eclectricity: "The town of Bowie Maryland on the outskirts of Washington has built a fountain based on the mathematical ideas of the great mathematician Fibonacci.The fountain's design embodies an intimate link between Fibonacci numbers and an irrational number known as the golden ratio, (1 + sqrt[5])/2, or 1.6180339887. . . . Ratios of successive terms of the Fibonacci sequence get closer and closer to the golden ratio. For example, the ratio 55/34 is 1.617647. . ., and the next ratio, 89/55, is 1.6181818. . ., and so on. Successive ratios alternate in overshooting and undershooting the golden ratio by decreasing amounts."
