All edges of a Koebe polyhedron are tangent to a sphere. Its face planes intersect the sphere in circles, which constitute a circle packing on the sphere and via stereographic projection a circle packing in the plane. This is the intro sequence of an upcoming film on Koebe polyhedra and minimal surfaces. It is self-contained and shows all the above mentioned connections in one continuous scene.
