Their collaboration dates back to 1995, and their work is described as "a set of experiments that test whether ideas such as authorship, nationality, borders, and democracy adequately describe today's increasingly global and consumerist society." Together they have had major exhibitions at the Dallas Museum of Art in 2006 and Kunsthalle Zurich in 2007.
