Musical Wallpaper

Why haven't I thought of this before?  Lately I've been dying to get some pattern up on my walls.  I'm not sure why, especially because I've never (ever) been a proponent for wallpaper at any point in my life.  Right now... well, that's a different story.  I recently saw a home treatment posting on Apartment Therapy about a home with Player piano music rolls on his walls as wallpaper.  How brilliant!  Maybe I'll give this a try.
