Modern high-tech architecture consists mainly of steel and glass. Glass is a great surface material and an ideal source for special effects like the distorted reflection in the picture. Reflection is happening when light intersects with a change in material such as air to glass. While walking through Buenos Aires, I was captivated by the effect produced by the mirror-like cladding of glass on the side of this office building. It looked like a canvas of glass panels on which a mosaic was created. This distorted mosaic is what gives these literally blank faceless facades a rather individual touch.
