We see just one image of an object placed in front of a mirror. And, we see more than one when the object is placed between two mirrors arranged like a 'V'. In this exhibit, we have three plane mirrors joined to form a triangular prism. Duck into the space and you will see a multitude of yourself ! The many faces you see are formed by reflection of reflections of your image. Such a multiple image forming instrument is called Kaleidoscope.
