Sphere from Icosahedron grid
Press 'S' to split every tri into 4 new ones
Mouse to rotate.
Press 'Up' / 'Down' to increase / decrease size.
Press 'F' to toggle filler
Press 'B' to toggle back-face culling
Press 'M' to toggle multi-coloring

Initially 20 triangles + 1 x 'S' = 80 triangles, + 2 x 'S' = 320 triangles
+ 3 x 'S' = 1280 triangles, ...
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.
