  <_description>
A mesh geodesic sphere of increasing and decreasing complexity.

A geodesic sphere is an icosohedron whose equilateral faces are
sub-divided into non-equilateral triangles to more closely approximate
a sphere.

The animation shows the equilateral triangles subdivided into four
coplanar equilateral triangles; and then inflated outward, causing the
sub-triangles to no longer be equilateral, but to more closely
approximate the surface of a sphere.
