Octahedrical Sunset

First try with a foldable more complicated than a cube. In fact, the octahedron is the dual of the cube: take the centers of the faces of a cube, join them, and you get an octahedron. Repeat this procedure for the octahedron and you get a... cube. The cube has 6 faces and 8 summits, while the octahedron has 8 faces and 6 summits (the tetrahedron is its own dual, the dodecahedron and the icosahedron are dual).
