Pine Cone by Michæl Paukner | www.substudio.com - "an illustration of the seed bearing scales on the base of a typical pine cone. It shows the golden ratio spirals clearly. The number of spirals in either direction are two consecutive Fibonacci numbers: 13 clockwise spirals and 8 counter clockwise spirals."
Pick up a pinecone...You may find eight spirals winding up to the left and 13 spirals winding up to the right, or 13 left and 21 right spirals, or other pairs of numbers. The striking fact is that these pairs of numbers are adjacent numbers in the famous Fibonacci series: 1, 1, 2, 3, 5, 8, 13, 21... The phenomenon is well known and called phyllotaxis...― Stuart A.
