Possibly drawn by James Gandy on an harmonograph. Because this looks so similar to James Gandy's work, I am going to attribute it to him, until someone can prove differently. [sh] The Fibonacci Spiral is created from the Fibonacci Sequence. The Fibonacci sequence is a mathematical succession of numbers in which each number is obtained by adding together the last 2 digits that came before it. The sequence goes as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233. The Fibonacci series is present all around us in many different forms such as flower patterns and shells. One of the best representations is in the sunflower. The pattern of seeds within a sunflower follows the Fibonacci sequence. [http://slideplayer.com/slide/6169228/]
