We begin with the Tetrahedron.

It is the 'lowest common denominator' of structural systems.

As part of our design, mid-edges have a Connector Hub for adding the dual-opposite Tetrahedron:

Dual Tetrahedrons form the vertices of the Cube and basis for the design of our "Tetra-Dome":

Tetrahedron mid-edge points also define the vertices of the Octahedron:

The Tetra Duals and the Octa:

Tetrahedron points are joined to make the Cube:

The Tetra Duals get a translucent covering:
