Sierpinski Tetrahedron

These are Sierpinski (pronounced sherpinski) tetrahedrons from order 0 to order 4.

This was my very first adventure with Blender, otherwise I would have made the models scale invariant, as the iterative construction generally implies. I put these together because the original order 5 model
