space-doubling mirror

A mirror placed in the corner of a room to create the illusion that there are other rooms on the other side of the mirror.

It occurred to me that placing a vertical mirror in the corner of my living room I could create the illusion of more space and enjoy that illusion, so two-weeks ago I dared to try that and it worked. A week ago I placed another what I'll call "space-doubling mirror" on the opposite corner. Looking at the first mirror reflected on the first, or in the second at the first, more than doubles the illusion of more space. Each mirror is 1 by 5 feet.
