Figure 13: Sunflower array configuration: the elements are numbered
starting from the center. In this case, 5 clockwise Fibonacci spirals appear,
red line, and 8 anticlockwise, in blue line. The interval of identificative
numbers between elements on the same Fibonacci spiral is always equal to the
number of spirals occurring, in this figure notice 22 − 14 = 14 − 6 = 8 and
24 − 19 = 19 − 14 = 5.
