'Toren op Zuid' by Renzo Piano

Interesting Architecture - The facade of this side is tilted and has a slanted pillar from the ground going into the center of the facade. The façade is clad with a green curtain wall system that is complemented by green lights distributed evenly over the glass facade. The lights work as a giant billboard and the patterns they create are easiest to see at night time or on an overcast day. These patterns change and move throughout the day.
