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

My work is about your seeing. There is a rich tradition in painting of work about light, but it is not light -- it is the record of seeing. My material is light, and it is responsive to your seeing.

I wanted the light to be the revelation. It has to do with what we value. I want people to treasure light.

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.

To have a certain new eight-and-a-hal f-minute-old light from the sun-to feel it physically, almost as we taste things-this is where you can work with light like that.

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.
