'Waldspirale' by Friedensreich Hundertwasser

Viennese artist, Friedensreich Hundertwasser, has designed what has become one of the more unique and visually stimulating buildings in the world. With over 1000 unique windows, individualized handles on windows and doors, a living roof, café, parking garage, restaurant, bar, playground, and a running stream, the Waldspirale in Darmstadt, Germany is an architectural wonder.
