This animation visualizes how the Chestahedron comes into being when a tetrahedron is opened up like a flower. As the tetrahedron opens, it becomes the Chestahedron, finally becoming a stellated octahedron. The stellated octahedron fits exactly within a larger tetrahedron that is exactly double the size of the original tetrahedron. The Chestahedron then comes out of the tetrahedron and spins into the bell shape.
