What the MUMOK museum could have done to Erwin Wurm is anyone's guess but he must have been pretty angry to throw a house at it! In actual fact, Erwin Wurm is a renowned Austrian sculptor and these pictures show 'House Attack' which was one of his more eye-catching installations. It was attached to the exterior of the biggest Austrian museum for international modern and contemporary art, MUMOK, to open Wurm's Keep A Cool Head exhibition in 2006. MUMOK's website describes the meaning behind the installation: “A symbol for conservative, small minded longings, the single-family house collides into the museum as a temple to the muses, and the museum itself now also becomes part of the sculpture.” The museum itself is a dark closed block clad entirely in Basalt-lava-stone and designed by Ortner & Ortner.
