At night, moving images of clouds and other images were projected from nearby exhibit buildings onto the Perisphere using a specially designed glass-mounted slides. The amount of light needed to project the images would have burned through regular film, so film slides were enclosed in glass. A new type of projector with a custom designed battery and the largest long-focus lenses ever commercially made were created to facilitate the Perisphere’s projections.
