Light is a powerful substance. We have a primal connection to it. But, for something so powerful, situations for its felt presence are fragile . . . I like to work with it so that you feel it physically, so you feel the presence of light inhabiting a space.

Science strives for answers, but art is happy with a good question.

My works are about light in the sense that light is present and there; the work is made of light. It's not about light or a record of it, but it is light. Light is not so much something that reveals, as it is itself revelation.

I was maybe 5 or 6, and my grandmother would begin sitting me in the Quaker meeting house. I asked my grandmother, 'What am I supposed to do?' and she said, 'Just wait, we're going inside to greet the light.' I liked that—this idea to go inside to find that light within, literally as well as figuratively.

We create the reality in which we live.

The sky is no longer out there, but it is right on the edge of the space you are in. The sense of colour is generated inside you. If you then go outside you will see a different coloured sky. You colour the sky.

I'm known as a light artist. But rather than be someone who depicted light, or painted light in some way, I wanted to have the work be light.
