Artful Space Dividers

I used bookshelves to divide my bedroom into different spaces.  These shelves separate my study from my bedroom.  Of course they look fine on the open side, where I can see and access my books but what about the plain backside?

By affixing small nails to the underside of the top shelf of the middle set, I was able to hook chains to the nails and run them over the top of shelves and down the backside.  I looped the chains around the hanging wire of a large framed piece of art which now dresses up the back of the shelves which form one of the walls of my bedroom.
