Examples of the 19th Century’s “Magic Lantern” and the “Optic Cinema” both use a light source on top of an image reflected from a mirror/glass onto a wall. The “Magic Lantern” displayed a single frame of artwork, while the “Optic Cinema” displayed a series of rotating frames to further tell a story. Furthermore, other than cave paintings, a tool that almost every technique of early animation used (including the “Magic Lantern” and the “Optic Cinema”) is some form of light manipulation. For example, projecting images based on their color brightness values or based on shadows.
