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.
(Hummm, neat idea, but uncertain on photos wrapping around the corner. The frames could meet up on the edge, but think the frames still might be best if they met in the corner but that each wall had its own photo frame.
