Sometime in the 1980s, Negativland used this educational film in a performance at a small planetarium in Oakland, California. I actually own a 16-millimeter copy of the film, but it is in such poor condition, I decided to present it courtesy of The A/V Geeks on The Internet Archive. I don’t remember much about the performance, but I’m quite sure my mother was in the audience. Maybe I can get Mark Hosler to comment on the film and performance. I definitely think some of my own obsessive compulsive behavior can be attributed to this film.
