16-mm print of Noll's computer animated stereoscopic movies of rotating four-dimensional Hyperobjects. Gifted by Noll to the Poly Archives in 2022.
As described by Noll, "the film shows four-dimensional hyper-objects: a 4D hyper-cube with perspective and linear projection from 4D to 3D; a tetrahedron; and a 4D hyper-sphere with dots randomly scattered on its surface. The 3D stereoscopic projections are displayed on each frame with the left and right images adjacent to each other. I believe the left image is on the right of the frame, and the right image is on the left; so that when projected, they could be viewed cross-eyed."
