The idea is simple - what you see everyday in the mirror is a reflection of yourself. Since humans are asymmetric, most people are shocked, and often embarrassed about how they look in photographs, and video footage. The mirror-mirror will help reduce the shock (of course for some people, this would need more than a double mirror).
Heres how it works: the mirror-mirror consists of 2 mirrors placed at right angles to each other, and at 45 degrees to the wall plane, thereby creating a prismatic niche (which would make a nice shelf). The working is similar to a periscope, but it reflects back to you instead of out towards something.
This could take getting used to especially if you try to use it for shaving.
P.S. - I just changed the name to avoid confusion with another idea. What are the odds that 2 ideas were posted at the same time with the same title?
