Lake Fibonacci

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."
