There is something breathtaking about the basic laws of crystals. They are in no sense a discovery of the human mind; they just "are" - they exist quite independently of us. The most that man can do is become aware, in a moment of clarity, that they are there, and take cognizance of them.

I might be in the basement. I'll go upstairs and check. We adore chaos because we love to produce order. I don't use drugs; my dreams are frightening enough.

Although I am even now still a layman in the area of mathematics, and although I lack theoretical knowledge, the mathematicians, and in particular the crystallographers, have had considerable influence on my work of the last twenty years. The laws of the phenomena around us--order, regularity, cyclical repetition, and renewals--have assumed greater and greater importance for me. The awareness of their presence gives me peace and provides me with support. I try in my prints to testify that we live in a beautiful and orderly world, and not in a formless chaos, as it sometimes seems.

Are you really sure that a floor can't also be a ceiling?

My work is a game, a very serious game.

Originality is merely an illusion.

It is human nature to want to exchange ideas, and I believe that, at bottom, every artist wants no more than to tell the world what he has to say.
