This is a Very Serious Post. Really. It's a follow-up to my previous post about icosahedral tesselation of the sphere (Earth). The idea is to divide the Earth as best possible into equal equilateral triangles. It's an extension of the cubed sphere that I use for gridding in TempLS. The next step is to subdivide the 20 equilateral triangles from the icosahedron in triangles and project that onto the sphere. This creates some distortion near the vertices, but less than for the cube.
So I did it. But not having an immediate scientific use for it, and having some time at Easter, I started playing with some WebGL tricks. So here is the mesh (each triangle divided into 49) with some color features, including some spherical harmonics counterpoint.
Naturally, you can move it around, and there are some controls. Step is the amount of color change per step, speed is frame speed, and drift is the speed of evolution of the pattern. It's using a hacked version of the WebGL facility. Here it is. Happy Easter.
