Shūsaku Arakawa was a Japanese conceptual artist and architect. He had a personal and artistic partnership with the writer and artist Madeline Gins that spanned more than four decades in which they collaborated on a diverse range of visual mediums, including: painting & printmaking, experimental filmmaking, performance art, and architectural & landscape design.

Conceptual art, also referred to as conceptualism, is art in which the concept(s) or idea(s) involved in the work are prioritized equally to or more than traditional aesthetic, technical, and material concerns. Some works of conceptual art may be constructed by anyone simply by following a set of written instructions. This method was fundamental to American artist Sol LeWitt's definition of conceptual art, one of the first to appear in print:In conceptual art the idea or concept is the most important aspect of the work. When an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. The idea becomes a machine that makes the art.
