1 tetrahedron + 1 cube + octohedron = 1 dodecahedron

Sitting on a table, a tetrahedron, a cube and an octahedron, all made of sticks attached to strings. At the push of a button pulleys, weights and counterweights are seen pulling the strings. The geometric figures begin to come apart, reform as a dodecahedron and eventually revert to their original state.

All is not as it would seem. Two glasses appear to contain slanting water. Two screws rotate to form the image of a glass. Two perforated discs rotate to create a triangle or circle.
A camera rotates simultaneously on two axes to create a seamless, hemispherical photograph of everything we can see around and above us.
