There recently has been discussion about spiral pictures and the Fibonacci effect. Here is my example to share from my accidental garden that illustrates it so well.
"The head of a flower is also subject to Fibonaccian processes. Typically, seeds are produced at the center, and then migrate towards the outside to fill all the space. Sunflowers provide a great example of these spiraling patterns."
it moves, you know, spinning ever so slowly, just enough to mess with your brain and eyes and heart. but i am right now eating some sunflower seeds so....[munch! munch!]
