corner gallery wall - without the specially made corner frames. Would need to be on a corner that is in an open area; this would be really overbearing in a tight hallway. But in the right space it could look amazing. Very art gallery.
Map Dresser - so fun, and maps are pretty inexpensive or something you already have! I can see this applied to a child's dresser or headboard or pictures on a wall.- would paint the dresser a dark color maybe red or blue for a more masculine room.
