I love the idea of a natural landscape superimposed in ultra clean design. I had grand plans to paint gold bamboo on my green bedroom walls. This is infinitely more elegant. And doesn't involve the ACTUAL outdoors.
Place painted foam board in the back of the bookcase, giving the look of a painted bookshelf w/out the commitment. Love this idea for a small book shelf next to couch. Good way to use yellow without committing to it in a big space.
