“It's been on my mind – what would something be like if it were unbalanced? It's been a vexing question for a long time. But it took the experience of working with radical kinds of symmetry, not just a rectangle, but a diamond shape, as well as extreme extensions of shapes, before I finally came to the idea of everything being unbalanced, nothing vertical, nothing horizontal, nothing parallel. I came to the fact that unbalancing has its own order. In a peculiar way, it can still end up feeling symmetrical. I don't know but what the very nature of our response to art is experienced symmetrically.”
