Caption: "The 7 first steps of the building of the Koch snowflake in a gif animation. Notice the parallel corresponding diameters present in the inner rhomboids--yes, just notice that." (Somewhat edited.)
The Koch snowflake is a fractal.
In this animation, we see the fractal structure being built up as the surface becomes more and more corrugated.
A fractal is an geometric object that shows self-similarity. It looks the same on every scale ideally.
Many structures in nature are fractal over some range of scales to some approximation---like the coastline of Norway.
