Projective Transformation:
“Cutting out around the edge of the map in the planar condition and bringing the parts back together makes an icosahedron. If the edges of the triangle are six inches, the folded system is the same as a 12-inch diameter globe. Of course, if you make an icosahedron, you will find it faceted into 12 equilateral triangles. If, however, the faceted icosahedron is compared to a 12-inch globe, the efficiencies of conveying information are equal between the two map systems.”
