A polyhedron that approximates a sphere, the sphere having an equator and two poles, the polyhedron having a plurality of polygonal faces, in which each vertex of the polyhedron is a junction of three or four polygonal edges, wherein each edge of each polygon is tangent to the approximated sphere at one point, each polygonal face being defined in a manner such that a circle can be inscribed therein that is tangent to each edge of the polygon at one point, wherein the polyhedron comprises two substantially parallel faces that are regular polygons said two parallel faces located at the poles to form polar caps and at least half of the remaining faces are selected from non-equilateral hexagons and pentagons, wherein the irregular polygonal faces are positioned in rings, including a first ring in a substantially equatorial position with respect to the approximated sphere and the centers of the inscribed circles of the polygons of more polar rings being at substantially the same latitude in each ring, and wherein successively more polar rings of polygons contain faces which are either equal in number or one-half the number of faces in the next most equatorial ring adjacent to each polar cap contains no more than one half the number of faces in the first ring.
