Friedensreich Hundertwasser (born 15 December 1928, died 19 February 2000) was an Austrian artist. He often called himself "Friedensreich Regentag Dunkelbunt Hundertwasser" ("Land-of-Peace Rainy-Day Dark-Colourful Hundred-Water") . Hundertwasser became known for designing buildings, but he also created stamps, painted, designed posters, and other works. He even designed a new flag for New Zealand, based on a local fern frond, called the Koru.
