The Oceans of Air exhibition at MONA, Tasmania, features Saraceno’s globular creations Aerocene 2.5, 4 and 5. “Once upon a time artists used to make beautiful things,” says David Walsh, MONA’s founder and owner. “Now, mostly, they want to change the world. Of the artists I know, Tomás Saraceno is the most likely to change the world. And he makes beautiful things.”
