Sun Yuan and Peng Yu, Old Persons Home, 2007. In the late 1990's, the duo started collaborating to create their deeply controversial and at times darkly humorous pieces. They range in scope and scale and medium, as they traverse topics such as death, violence, and morality while exploring the human condition. Below is a link to their website, with more photos as well as descriptions of their various projects.
