Phantasmagoria

Phantasmagoria ( American pronunciation , also fantasmagorie, fantasmagoria) was a form of theatre which used a modified magic lantern to project frightening images such as skeletons, demons, and ghosts onto walls, smoke, or semi-transparent screens, frequently using rear projection. The projector was mobile, allowing the projected image to move and change size on the screen, and multiple projecting devices allowed for quick switching of different images. Invented in France by a Belgian physicist in the late 18th century, it gained popularity through most of Europe (especially England) throughout the 19th century.
