The answer to the riddle, what turns everything around without moving, is a mirror. A mirror reflects everything around but it does not move. The images in the mirror are returned using specular reflection, which reflects the light without diffusing it.
When light hits the smooth surface of a mirror, it reflects the incoming image back out. It does not give a reflection from the mirror’s viewpoint, but a light print of the image that is being directed into the mirror. There are different types of mirrors and the mirror does not need to have a flat surface to reflect images.
