A triskelion or triskele is a motif consisting of a triple spiral exhibiting rotational symmetry. The spiral design can be based on interlocking Archimedean spirals, or represent three bent human legs. It's first known use was in Malta around 4500 BC. It is also found in ancient Irish culture, ancient Greece, Japan, Tibet and elsewhere. This symbol is associated with motion and progression. Read more here: https://en.wikipedia.org/wiki/Triskelion

Golden Ratio Spiral. Fibonacci Spiral. In geometry, a golden spiral is a logarithmic spiral whose growth factor is Phi, the golden ratio. That is, a golden spiral gets wider (or further from its origin) by a factor of Phi for every quarter turn it makes. Fibonacci spiral, which is constructed similarly to the above method except that you start with a rectangle partitioned into 2 squares and then in each step add to the rectangle's longest side a square of the same length. Since the ratio between consecutive Fibonacci numbers approaches the golden ratio as the Fibonacci numbers approach infinity, so too does this spiral get more similar to the previous approximation the more squares are added.
