Fibonacci Symbol - Golden ratio

Fibonacci Golden Spiral - Golden Ratio

In geometry, a golden spiral is a logarithmic spiral whose growth factor is φ, the golden ratio. That is, a golden spiral gets wider (or further from its origin) by a factor of φ for every quarter turn it makes.

The Fibonacci sequence is fascinating to mathematicians, artists, musicians, and a host of other people due to its ascending pattern that can be seen in both sacred geometry and nature itself. It is both mathematical and spiritual at the same time.
