Hi everyone. Ok my parents are building a new house and my rooom is going to be by the basement so its basicaly part of the basement but there's a wall. I was thinking about my new room yesterday and I thought wouldn't it be cool if instead of having a door lead to my room having a walk thru mirror in the wall so here's what I thought I'd like.

My dads a craftsman and insulating the house so if he could put a mirror in the wall that slides a couple feet an locks in place when it's shut and to keep me from going through. If I put some of that black elastick material over it with a slit down the middle if you get my point. If so can you give me some feedback and other tricks I could put into my room. thx
