Actually if you're going to go with a darker shade like that green, I think you need more stuff on the walls and in the corners that "brighten" the room. My god, my wife has made me gay....
We haven't gotten around to the decorating yet. You are right though. We both are indirectly in the business of making maps and imagery. We have a sizeable collection that we are in the process of matteing and framing.
Oh yeah, I totally agree with your post before the decorating advice.
