The image reminds me of a sliding tile puzzle I had as a child. The tiles, when completed, showed a picture or sequence of numbers which could be scrambled or arranged by using the one empty space in the frame to move tiles one at a time.
The individual windows in this image appear to have been shuffled and need reorganised into a complete reflection.
The building appeared to house those involved in media, TV or radio, and is in Sophia, Bulgaria.
