Airplane Window Building?

I guess this is another abstract shot. This is was taken around Mellon Square Park - one of the cool skyscrapers in the area. The unusual windows caught my attention immediately and the way the shade cut through the middle made it kind of cool. There were three or four other buildings that were similar but different, but the set of three windows pattern turned me on to this one. Whether you look up close or from afar, Pittsburgh is amazing.
