Notes and Credits

Trying out some alternatives for distributing a limited amount of points/dots/faces to represent a sphere.

Starting out with a Icosahedron vertices form three orthogonal golden rectangles. Source: https://en.wikipedia.org/wiki/Regular_icosahedron

Learned a lot from drawing equilateral triangles and implementing Sierpinski.
