Years ago, when I had my contractor do the game room, I asked we get extra creative - make me a window in a wall of the closet, lol.
I told him if I'm in the game room (or the closet, which now houses the video games), I want to get that impression you're at the local tavern or watering hole (and looking at the neon that they typically hang in their window).
I've since 'junked up' the window with a few other things, but I think the idea turned out pretty cool.
