Click flag. See a diversity of spirals arising from turning the golden angle, 137.5077... degrees, the angular version of Phi, the golden ratio. Why do these patterns result from this very brief and simple code?
The colors show many different spiral patterns, some clockwise, others counterclockwise. The sprite starts from the center and turns the golden angle (137.50776405...degrees). This golden angle turn is the best way to fill space, and causes the number of clockwise and counterclockwise spirals to be Fibonacci numbers (such as 5, 8, 13, 21, 34, 55, 89, 144....), but hard to count in this one. Sunflowers, daisies and many other flowers have florets that form these type of spiral patterns. But something more is going on here. ???
