Infinity mirror

The infinity mirror (also sometimes called an infinite mirror) is a configuration of two or more parallel or angled mirrors, which are arranged to create a series of smaller and smaller reflections that appear to recede to infinity. Often the front mirror of an infinity mirror is half-silvered (a so-called one way mirror), but this is not required to produce the effect. A similar appearance in artworks has been called the Droste effect. Infinity mirrors are sometimes used as room accents or in works of art.
