What is a dark room where outside images project onto the opposite wall?

Explanation:
Camera obscura is a darkened space where light from the outdoors enters through a tiny opening and casts an image onto the wall opposite the hole. The image appears upside down because light rays cross as they pass through the opening, and adding a lens can make the projection sharper. This device is a foundational optical concept that helped lead to photography, and it’s different from a Magic Lantern (which projects slides or images) and a Thaumatrope (a simple motion toy), as well as from ordinary photography that captures images rather than simply projecting them.
