Two-Dimensional Building
Another example of a photo doing tricks on your brain is this two-dimensional building which seems to only have a front and no back. It almost looks like it is a movie set with just a glass wall as a front. The skies are probably reflecting on the other side of the building making it look like this.
We are as confused as you are. We still do not understand how the building is looking totally flat and there is not even a slight hint of the other wall of the building. Pictures are totally misleading at times.
