Grainger's Elemental Periodicity with "Concentric Spheres Intersecting Orthogonal Planes" Formulation

From Tony Grainger, an Elemental Periodicity formulation with concentric spheres intersecting orthogonal planes.

Tony writes:

"I hand sketched this periodic table about a decade ago and placed it on my cubicle window at UTAS, with minimal comments from work mates. It bears some similarity to other formulations in the database, especially when cut along the left axis and laid flat. The concept of all elements of a period being aligned along orthogonal planes cutting a sphere was inherent in the original sketch. When I began using SVG about five years ago I realised I could draw this as a real projection of the 3D model. It was on the back burner, until I found the original sketch during a tidy up."

There are two images of this 3D formulation: an "inside_corner_below/outside_corner_above" (top image) and an "outside_corner_below/inside_corner_above" lower image.
