One thing that sea shells always remind me of is the golden ratio. It is something I learned about design while in school - the ratio of 1.618 to 1. It's found in both nature and architecture. The golden ratio is found in the nautilus shell, pine cones, roses and sunflowers to name a few. The Egyptians and Greeks used the ratio in architecture (Great Pyramid of Giza, and Parthenon). Even our bodies have the golden ratio in the relationship of our eyes, nose, ears and mouth.
The mathematician Fibonacci developed the Fibonacci Series based on the ratio (it's not exact, but close): each number of the series is the sum of the two preceding number.
So now you know how my brain works...show me a sea shell, and learn all about math! I am what I am! I'm not sure exactly sure what this has to do with my sketching, doodles and art. Stay tuned to find out!
