The electrotachyscope is an 1887 invention of Ottomar Anschütz of Germany which presents the illusion of motion with transparent serial photographs, chronophotographs, arranged on a spinning wheel of fortune or mandala-like glass disc, significant as a technological development in the history of cinema.
A Geissler Tube was used to flash light through the transparancies to provide a weak projection to a single person or small audience through a small window.
