Fractal Tetrahedron

A tetrahedron is divided into four tetrahedra and one octahedron. Then each tetrahedron is divided again in the same way. This process could be continued to form a fractal structure. A face of the divided tetrahedron would become a Sierpinski sieve and the 3D tetrahedral parts would form a tetrix (or Sierpinski sponge).
