... it's not an illusionistic thing. It just seems as though there are forms in some experience in your life that have an excitement for you….. those sort of forms in your experience do, in some way, not dominate, but they become the things that you are involved with. I don't mean that squares becomes windows; after all, squares becomes heads, they becomes everything you know. I don't mean it in that sense. A curve or line or rhythmical relation do have, in some way, some psychological bearing, not only on the person who looks at them after they've been conceived but also they do have a lot to do with the creative being who is involved with wondering just how exiting it can be..
