43 Animates a mesh geodesic sphere of increasing and decreasing complexity.
45 A geodesic sphere is an icosohedron whose equilateral faces are
46 sub-divided into non-equilateral triangles to more closely approximate
49 The animation shows the equilateral triangles subdivided into four
50 coplanar equilateral triangles; and then inflated outward, causing the
51 sub-triangles to no longer be equilateral, but to more closely
52 approximate the surface of a sphere.
