Yes, I was just meditating on the cube turned with the points facing up and down as the would be if the above and below were attempting to merge.

A diamond shape.

The 'funny' thing here and bear with me, was there was a 'plug' in the bottom of the top tetrahedron and its 'female' aspect below.

10 becomes 8 with the merge.

The X, Y, and Z axises merge together in the center, focusing 8 'capstones' instead of the 2 the tetrahedronal structure allowed.

I saw how that references the square and compass as well as a coming together of these tetrahedrons, the 'plug in' and a further merge within creating in essence....
