2.Ai weiwei

Ai Weiwei is a famous chinese artist. He does many types of artwork. That include: architecture, curating, photography, and film. he uses many mediums to create his artwork. His uses doors, lights, bikes, etc., but he likes to use a lot of different types of chairs. Chairs are funtional art, that he uses to create his work, by arranging them into to ways that defeat their purpose. I believe the effectiveness of this was "to create a strategy of defiance of the status (symbol, value, function) of monuments that functions like an autoimmune deficiency: in presenting monument-like elements the artist undermines the very essence of commemorative structures, imploding their significance."
