In the AI Interview with Eliasson, the artist cites Robert Irwin, who was associated with California Light and Space movement, as an important influence (the exhibition catalog for the SFMOMA exhibition includes a dialog between the two artists).
Mid-Manhattan Art has several books on Irwin, including the catalog for Robert Irwin's exhibition at the Museum of Contemporary Art, Los Angeles in 1993, Lawrence Weschler's biography Seeing is forgetting the name of the thing one sees : a life of contemporary artist Robert Irwin, and a book about Irwin's design of the Central Garden at the Getty Center in Los Angeles.
