I did a 3D graphic interpretation with SQ as a four colored transparent cone
suspended in a crystal sphere of DQ some time back. The ability to view it
at all angles allows for multiple POV interpretations. Circular (Venn) top &
bottom, stacked hierarchy from sides and everything in between. PM me and I
send you a copy.
