Whatever happens to the art world, art will go on regardless. As for obscurity, it looms just over the horizon beckoning us all. Why worry.

I have been using the computer as a work aid since the mid-90's. It is extraordinarily well suited to how I think and work and has transformed my practice. Nearly everything I have done in the past 15 years would have been impossible without it. I use the computer for drawing, composing and colour planning everything, from postage stamps to paintings to architectural-scale installations.

It's just that some things more important for this and less important for that, and this is true regardless the style of the art.

I've taken away everything I could think of, and yet what remains is enough. These days many more people come to my work, and once they see my work they will always recognize it.

When I started teaching in the late 60s, in a time of student revolutions and changes, they changed in question of society and authority.

Usually people start with painting and then go on to make installations; my painting came from installation.

The identifying personal association with objects, which are not personal, is an important modern experience - our real association, the strands of our feelings about the objects that surround us. It's also because they are so familiar, we don't think of them as important in the world, but actually they are the world. We are living in a very material world.
