The Sunflower

In a Fermats spiral, the angle of seed-succession (137.5) approaches the golden ratio, which – in popular terms – can be explained as the (limit)ratio between succeeding numbers in the Fibonacci sequence (0, 1, 1, 2, 3, 5, 8, 13...). The seeds are ordered sequentially and placed according to their index number in the flower - read more on Wikipedia. This Python script generates a scalable “sunflower” using tricoloured seeds and the mathematics of the Fermats spiral.
