It's really terrific to see Pittsburgh recognize the Mattress Factory.

We're made for the light of a cave and for twilight. Twilight is the time we see best. When we dim the light down, and the pupil opens, feeling comes out of the eye like touch. Then you really can feel colour, and experience it.

I have made things for Calvin Klein and other designers, and it's interesting to see the way each person approaches it.

Sometimes I'm kind of cranky coming to see something. I saw the Mona Lisa when it was in L.A., saw it for 13 seconds and had to move on.

I like to use light as a material, but my medium is actually perception. I want you to sense yourself sensing - to see yourself seeing.

I like to work with it so that you feel it physically, so you feel the presence of light inhabiting a space. My desire is to set up a situation to which I take you and let you see. It becomes your experience.
