I have triangles clipped inside a circle with text wrapped around the circle and that’s as far as I will get with this tonight. I want to go with random marching triangles within a circle and eventually on the surface of a sphere, which I will definitely want to animate! With random marching triangles grouped into polygons which are land or sea I can get the areas and keep a running tabulation of both as we add areas. When I get to a complete spherical polyhedral world map then I will have overlapped the starting far hemisphere with the near hemisphere.

It occurs to me that I can make the parent div a polygon based on all the internal child divs by changing it over time...
