I don't grow up. In me is the small child of my early days.

In mathematical quarters, the regular division of the plane has been considered theoretically. ... [Mathematicians] have opened the gate leading to an extensive domain, but they have not entered this domain themselves. By their very nature they are more interested in the way in which the gate is opened than in the garden lying behind it.

If I am not mistaken, the word "art" and "artist" did not exist during the Renaissance and before: there were simply architects, sculptors, and painters, practicing a trade.

Hands, are the most honest part of the human body, they cannot lie as laughing eyes and the mouth can.

All my works are games, serious game.

I came to the ... open gate of mathematics. From here, well-trodden paths lead in every direction, and since then I have often spent time there. Sometimes I think ... I have trodden all the paths ... and then I suddenly discover a new path and experience fresh delights.

I am always wandering around in enigmas. There are young people who constantly come to tell me: you, too, are making Op Art. I haven't the slightest idea what that is, Op Art. I've been doing this work for thirty years now.
