The full color version of the 64 tetrahedron grid makes it easy to see the main geometries that form a pattern within it. There is an outer large red tetrahedron pointing up, and a blue pointing down. There is a large purple (pink?) cuboctahedron between them. At the centre 6 white lines meet to show the symettry axes. Surrounding the center there is a yellow octahedron containing a smaller green cuboctahedron. The rest of the form is made of black octahedrons. Together these reveal the core hexagonal/triangular/cubic symmetries of 3D space in the same way the flower of life reveals...
