The space between things is important to me. The projections, that darkness between the words or the images is very important.

So it sort of dawned on me that you have to build into your work the fact that it's going to be shown in different kinds of places and different kinds of light. And the fact that the surroundings and where you're going to be shown is always changing, so that should really not affect the meaning of the work. It should be part of what the work is about.

A word refers to something in the real world and so, in a way, does a photo. It's not the thing itself, but it's a kind of suggestion of where you might look for that thing.

I am a very lucky artist in the sense that I have had all my life a lot of opportunities to do what I want to do.

I think words speak to us even though they may be written on a wall. So we hear them in our mind. We say it to ourselves. But they are also visual things. You draw them. They are designed. They are colored. They have a certain size. I put them in a certain place. So they are objects that have to be - artistic decisions have to be made in terms of the color and the size and the line and whatever.

I may have a lot of political opinions but it doesn't necessarily come into my work. I keep the two worlds separate.

I think you say the word in your mind anyway, you know. When you look at a word, you say it.
