Near the green banks of the Danube Canal is Vienna's most whimsical museum, showing the imaginative, fantastical works of painter and designer Friedensreich Hundertwasser (1928–2000). Hundertwasser was one of the world's most famous architects, and this is a fitting memorial. A lover of nature, the architect created uneven floors, irregular corners, trees growing out of roofs and windows, and oddly shaped, different-size windows. The museum is filled with his paintings, drawings, and architectural projects (many of which were never built). The museum is also a venue for temporary exhibitions of international artists. Previous shows have focused on such artists as Picasso, Cecil Beaton, and Michel Compte. The tiled black-and-white checkerboard exterior has been compared to a Klimt painting seen through a kaleidoscope.
