Cool, but one must ask, "Why!"

Belgian architect group, Gijs Van Vaerenbergh, built a church in Belgium, and it’s pretty plain from certain angles. From others, the structure reveals itself to be something else entirely: a building that’s almost entirely see through. 

The project, named “Reading Between the Lines,” is a composition of 100 layers of stacked steel, that are equidistantly staggered in a way that illusively change in appearance based on where the viewer is standing.
