Audioscopiks is a 1935 American short documentary film directed by Jacob F. Leventhal and John A. Norling.
The main point of the short was to show off 3-D film technology.
Current prints appear to have faded to a crimson-cyan color, causing ghosting to occur when viewed.
They are then given a demonstration of 3-D with various objects moving towards the camera, including a ladder, a baseball being thrown and a woman on a swing.
Smith narrates each short clip, most being 20 seconds or less.
