I'm going to do a frame collage like this for the living room. Not sure yet if I want the frames to be all the same color or not. Some will have pictures in them and some will have personally crafted pictures/collages.
I think this was designed for a pre-teen/teenager, but there's a lot I like for a guest bedroom/home office. Love the built in desk and storage and love the blue, white, bright green color palate. The ceiling fixture is especially cool.
