Stunning contrast, and wonderful shadows...I've been fascinated for a while on this subject and how spirals are found in nature everywhere including galaxies. That's a great video I haven't seen yet, thanks. Check out this video with ants that looks like a galxy Ants Spiral
I love the video. I used to teach fibo to my Grade 3 kids to WOW their parents.
It was always amazing how many examples they found on their own too.
Anyway, the pinecone demonstrates it beautifully. The one that was most amazing to kids was those huge sunflower heads.
