By Keenly Confronting The Enigmas That Surround Us, And By Considering And Analyzing The Observations That I Had Made, I Ended Up In The Domain Of Mathematics. Although I Am Absolutely Without Training In The Exact Sciences, I Often Seem To Have More In Common With Mathematicians Than With My Fellow Artists.

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.
