Mathematics and Sunflowers.
Fibonacci numbers can be called natures numbering system. The sequence itself appears so simple. Yet, it appears over and over in nature, from sea shells to pinecones, flower petals to pineapples, from a grain of wheat to a galaxy.

If you look closely at the center of a sunflower there are two spirals, one moving clockwise and one moving counterclockwise. If you count the
spirals in the center of the flower you will find that they are sequential Fibonacci numbers such as 8 and 13. These beautiful double spirals were the inspiration for this design.

For those mathematicians out there, I know the number of spirals are not Fibonacci numbers, but are a compromise for ease of design.
