An infinity mirror is a room filling optical illusion that creates the appearance of an endless tunnel of light or space using two or more parallel or angled mirrors.

The mirrors are positioned so that light reflects between them, creating a series of smaller and smaller reflections that appear to recede into infinity. Infinity mirrors can be used in a variety of settings, including homes, offices, bars, and clubs. They can be customized to create a desired ambiance, from relaxing and soothing to vibrant and energetic. Some infinity mirrors have LED lights between the mirrors that can be programmed to change colors or respond to sound or music. Here are some things to know about infinity mirrors:

• The front mirror of an infinity mirror is often half-silvered, but this is not required to produce the effect.
• The effect is similar to the Droste effect, which is sometimes seen in artworks.
• In theory, mirrors facing each other can create infinite reflections, but imperfections in mirrors make this effectively impossible.
• The infinity mirror effect can also occur in screen-sharing applications when the user shares their entire screen, which creates an infinite loop of screen shares.
