I looked at a house recently that had a gameroom with some pins and arcade machines, and also had a turnstyle. It immediately caught my attention and I checked it out, but if was off to the side and we didn't have to "use" it to enter or leave the room. It was purely decorative and you could go through it if you wanted, but not if you didn't.
I was neat though, but purely as a decoration, not function.
Luck!
