The universe is real, but you can't see it. You have to imagine it.

My fingers always seem busier than my mind.

My whole theory about art is the disparity that exists between form, masses and movement.

If you can imagine a thing, conjure it up in space then you can make it... The universe is real but you can't see it. You have to imagine it. Then you can be realistic about reproducing it.

The next step in sculpture is motion.

To most people who look at a mobile, it's no more than a series of flat objects that move. To a few, though, it may be poetry.

Why must art be static? You look at an abstraction, sculptured or painted, an entirely exciting arrangement of planes, spheres, nuclei, entirely without meaning. It would be perfect but it is always still. The next step in sculpture is motion.
