Sequence Hats
Description: A geometric abstract composition featuring the Golden Ratio spiral. The spiral is depicted with shades of blue and teal, with shadowing to create a sense of depth. The background is black. The spiral is divided into squares of decreasing size, following the mathematical sequence.
Description: Today is Fibonacci (Leonardo of Pisa) Day. Fibonacci sequence starts like this: 0,1,1,2,3,5,8,13 and so on. Each number is the sum of the two numbers before. When using squares with those widths we get a spiral like the one on the tail of the chamaleon. You can find it also on: flower petals; seed heads; pinecones; shells; spiral galaxies etc.
