Texture & pattern: Fibonacci spiral patterns appear in many plants, such as pinecones, pineapples, and sunflowers. The patterns consist of spirals that curve around a surface both clockwise and counterclockwise.

Fibonacci Sequence - pattern of growth.the Fibonacci spiral - the golden ratio - a mathematical form found everywhere in nature from the shape of the galaxy, to patterns in plants, to the curl of a wave, to the double-helix spiral of our own DNA

Fibonacci Spiral - Golden Spiral Logarithmic spiral whose growth factor is Ï†, the golden ratio - gets wider (or further from its origin) by a factor of Ï† for every quarter turn it makes.

The Golden Rectangle, the Golden Triangle, and the Golden Pyramid, all based on the Golden Ratio are all appear prominent in the work of Leonardo Da Vinci. He referred to the Golden Ratio as the "divine proportion".
