James Turrell: Gard Blue (1968-2002) This work is a Cross-Corner Projection piece, part of a series of some of the earliest light works that Turrell made. This work uses a projector to create light in a shape that seems to have weight and mass. "It is about perception, using light as a material to influence or affect the medium of perception. We live in this reality we create,and we're quite unaware of how we create the reality. So the work is often a general koan into how we go about forming this world in which we live, in particular with seeing".

James Turrell: Catso, Red (1967-1994) What appears to be a red cube in the corner of the gallery is a red square of light projected diagonally across the room. “It’s very important to me that you see it one way at first, and then it reveals itself as something else. Then you go back again and see it the initial way again.”

Turrell's installation "Alta (Pink)" as part of the "Cosmic Wonder" exhibition at San Francisco's Yerba Buena Center for the Arts in 2006:“We think of color as a thing that we're receiving. And if you go into one of the sky spaces, you can see that it's possible to change the color of the sky. Now, I obviously don't change the color of the sky, but I changed the context of vision.”

'Spread' 2003 NOTES: - His art is not an object but an experience in perception, manipulating light rather than paint or sculptural material. - Works full of purity and emotional resonance - Makes light palpable
