Computer-animated 3D stereoscopic movies made at Bell Telephone Laboratories, Inc. in 1965-66. Shown are: random line object (kinetic sculpture); computer-generated ballet; 4D hypercube, hypersphere, and other 4D objects; and molecular motion. The computer animation was programmed in FORTRAN on an IBM 70940 computer and plotted on a Stromberg-Carlson SC-4020 microfilm plotter.
