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

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.

Each day is a different length of time and that gives a different length to the cusp between light and darkness or darkness and light.

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

Generally, we use light to illuminate other things. I like the thingness, the materiality of light itself. So it feels like it's occupying the space, making a plane, being something that was there, not just passing through. Because light is just passing through. I make these spaces that seem to arrest it for our perception.

One way to understand light in the ocean of air is by flying it. Life in the air is an extension of perceiving.
