Charles and Ray channeled Charles' interest in photography into the production of 125 short films . From their first film, the unfinished Traveling Boy (1950), to Powers of Ten (re-released in 1977), to their last film in 1982,  their cinematic work was an outlet for ideas, a vehicle for experimentation and education. The couple often produced short films in order to document their interests, such as collecting toys and cultural artifacts on their travels. The films also record the process of hanging their exhibits or producing classic furniture designs. Some of their other films cover more intellectual topics. For example, one film covers the purposely mundane topic of filming soap suds moving over the pavement of a parking lot. Powers of Ten (narrated by physicist Philip Morrison ), gives a dramatic demonstration of orders of magnitude by visually zooming away from the earth to the edge of the universe, and then microscopically zooming into the nucleus of a carbon atom.
Charles Ray is widely regarded as one of the most significant artists of his generation. He is best known for his sculptures of altered and refashioned familiar objects. In 1993 Ray made Firetruck , a 12-by-47-foot replica of a toy fire truck, which he "parked" in front of the Whitney Museum of American Art during that year's biennial exhibition. In 2007 the artist completed a ten-year project—a re-creation in Japanese cypress ( Hinoki ) of a fallen and rotting tree he had found in a meadow, hand carved by Japanese master woodworkers. In 2009 Ray installed Boy with Frog , his first outdoor commissioned work, at the Punta della Dogana in Venice. Grand in size and realized with a smooth white finish that references the important tradition of marble sculpture in Italy, it depicts a boy holding a goliath frog above the Grand Canal. In 2015 the artist completed Horse and Rider , a ten-ton equestrian statue machined from solid stainless steel, with Ray himself as the rider.
Ray (born 1953) has exhibited at Documenta IX (1992), Venice Biennales in 1993 and 2003, and five Whitney Biennials, and he has had one-person museum exhibitions in Basel, Chicago, London, Los Angeles, Milan, Bern, Vienna, and Oslo, among other cities. Ray lives and works in Los Angeles.
