In the GEM in The Hague I saw a retrospective of one of the best known contemporary artists of our day Austian" Erwin Wurm (1954)". His work has evolved into a humorous universe in which he himself, his audience, articles of clothing, thoughts or actions can all become pieces of sculpture.
It was a very funny exhibition in which you could make an artpiece yourself by putting a chair on your head, or a broomstick between your legs. He even got model" Claudia Schiffer" so far to do so as you can see here and worked with the "Red Hot Chilli Peppers" for their clip.
