Tetrahedrons

I have for a long time been interested in Tetrahedrons, the first platonic solid. A simple four sided form with obvious mathematical interest but visually difficult to rationalist, never having an obvious base and seeming unstable. So the fascination between these two ways of understanding becomes even richer.
The large elongated Tetrahedron has images of a bomb or a boat. The smaller Tetrahedron has the words Confusion, Fission, Fusion and Diffusion written on each of its nodes.
