Answer 2

Shadowgraphy or ombromanie is the art of performing a story or show using images made by hand shadows. It can be called "cinema in silhouette". Performers are titled as a shadowgraphist or shadowgrapher.

This art has declined since the late 19th century when electricity became available to homes because light bulbs and electric lamps do not give off good shadows and because cinema and television were becoming new. Shadows are greatly defined by candlelight; therefore hand shadows were common in earlier centuries.
