Pyramids of Montauk - Preston Nichols & Peter Moon.

The book talks about Sacred Geometry, and the Platonic solids, tetrahedron, icosahedron, cube, dodecahedron, and octahedron. When you rotate the tetrahedron through space you can generate the others, and one of the descriptions shows two solids, then four, on and on, which reminds me of nothing so much as the division of the fertilized egg in conception.
