reflector

A road mirror or reflector is a useful device to avoid car accidents: it is put close to crossing, where a secondary road meets the main one. These mirror have a circular shape and are stereoscopic, that is they provide a three-dimensional view of a scene. As you can see, in the pictures the world is seen through these peculiar appliances that reflect a strange and deformed reality. The funniest image is the about people on a roller coaster.
