Mirrored Walls

I've been thinking about mirror a lot lately. What do you think of a room that is mirrored? My mind goes instantly to those suburban dining rooms which are tragically mirrored...Or the city apartments that were mirrored back in the 80s - Oy Vey.
However, I think these images posted are pretty fab, don't you think? Look at the famous mirrored bathroom in Miles Redd apartment above, or this living room by Bunny Williams below.Remember I talked about mirroring my backsplash in the kitchen HERE? I keep returning to that idea. So -yah, or nah?
