Wiki-The magic lantern has a concave mirror in front of a light source that gathers light and projects it through a slide with an image scanned onto it. The light rays cross an aperture (which is an opening at the front of the apparatus), and hit a lens. The lens throws an enlarged picture of the original image from the slide onto a screen.Main light sources used during the time it was invented in the late 16th century were candles or oil lamps.
The notorious 'rat-catcher' routine, made possible by using 2 pieces of moving glass, during the show the audience would provide the sound effects of the slide...
...Linked to the Planetarium attractions around the country, and even products based around the same sort of idea as the lantern, the product used in households put on a light show using beams of light that can rotate and change through the devices' projector.
