• Gyromorphosis, 1958, 7 min.
  In Gyromorphosis, film maker Hy Hirsch strives to display the kinetic qualities of the New Babylon structures of Constant Nieuwenhuys. One by one he puts parts of the structures in motion and films the details with colored lighting having them overlap each other, appear and disappear. He creates a sensation of acceleration and suspence suggested by the work itself.

We have no information on the availability of this film:

• Constant oder der Weg nach New Babylon (Constant or the route to New Babylon), 1968, 55 min.
  For ten years Constant worked on his New Babylon project as a reaction to architectural and social realities. Film maker Carlheinz Caspari followed Constant and his vision.
