Last year, MIT established a Center for Art, Science & Technology to integrate arts into its engineering-centered curriculum. As the first artist in residence at the center, MIT picked Tomas Saraceno, whose works resemble strange, epically large science fair projects. (In fact, they have sometimes been criticized as experiments rather than art). Saraceno was born in Argentina, raised in Italy, but prefers to say he’s from Planet Earth, floating above national boundaries like the clouds.
