Title: Journey to the Center of a Triangle
Url: https://archive.org/details/journey_to_the_center_of_a_triangle
Publisher: Internet Archive (Firm)
Description: Created by Bruce and Katherine Cornwell, this film from 1976 includes no narration but still manages to demonstrate a number of geometric properties of a triangle, including incenter and circumcenter, through simple animation set to Bach's preludes 8 (Eb minor) and 12 (F minor). The film was created using a Tektronics 4051 Graphics Terminal and originally appeared in vivid color. Unfortunately, as the description to this animation notes, "all of that color is pretty much lost now, between prints fading and/or transfers to the VHS, and then viewing them on a computer screen which has a much more limited color gamut." Nevertheless, this animation still offers an entertaining and educational experience. Those who enjoy this film can learn more about the Cornwells through a link in the description.
