Arguably the most popular Austrian artist, Friedensreich Hundertwasser was also one of the country's most controversial. Whether designing flush-free toilets or peace flags, building apartments with slanting floors or filming documentaries in the nude, this brilliant iconoclast left evidence throughout the world of his talents and passions. Hundertwasser's beloved KunstHausWien is home to the only permanent collection of the artist's works. More than 200 colour illustrations display the characteristics of Hundertwasser's style: his penchant for the circular over the linear; his political posters and postage stamp designs; and, his architectural projects both unrealized and completed. A summary of Hundertwasser's work by his close friend Joram Harel offers an intimate portrait of an often misunderstood genius. This colourful retrospective conveys Hundertwasser's passion, energy, versatility and commitment to his personal ideology.
