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

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.

A mobile is an abstract sculpture made chiefly out of sheet metal, steel rods, wire and wood. Some or all of these elements move, propelled by electric motors, wind, water or by hand.

To an engineer, good enough means perfect. With an artist, there's no such thing as perfect.

That others grasp what I have in mind seems unessential, at least as long as they have something else in theirs.

My fan mail is enormous. Everyone is under six.

My fingers always seem busier than my mind.
