A prominent sculpture near the Miracle Mile in San Rafael is commemorating the 40th anniversary of a Marin-based student-exchange program. A giant globe made of stainless steel sits at the top of the 12-foot-tall sculpture, which is the creation of Fairfax artist Susan Pascal Beran. The globe is ringed by images of flags from 60 countries, and inside it are colorful, miniature houses and figures holding hands.
