This would make a really cool art installation where you start at the top of a multistory building and keep walking through and turning right before going downstairs to the next room where you walk through and turn right before going downstairs to the next room... Etc etc.

If all the furniture got progressively smaller as the walls and ceilings progressively closed in, it would feel just like this picture.

Or you could leave everything the same size and it would still make for a surreal experience going down, through, right, down, through, right, etc until popping out into the street - at that last set of stairs you'd be certain the door in front of you would lead straight into the identical living room from every other floor. Seeing the street instead would be a real mindfuck.
