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.

The basis of everything I do is the universe.

I have been making wire jewelry - and think I'll really do something with it, eventually.

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

You see nature and then you try to emulate it.

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.
