Paolo Salvagione is an artist who works at the intersection of engineering, participation, and levity. He has exhibited at such San Francisco Bay Area venues as Aggregate Space, Headlands Center for the Arts (artist-in-residence), MacArthur B Arthur, Performance Art Institute/Zero1 Biennial, Root Division, San Francisco Center for the Book (artist-in-residence), and Seager Gray Gallery, and was tapped by Regensburg Theater in Germany to be the first non-native to serve as artist in residence at its annual festival. In his art, Salvagione has sent his studio visitors out one second-story window and in another on a 900-pound steel wheel, created scent-based sculptures that use smell as a touchstone for memory, and mixed pure geometry and pure fun in the form of ten oversized swings — with the implicit suggestion that visitors compete. He will have a 2014 solo show at the Luggage Store in San Francisco. And he worked, for over a decade, as lead engineer on the 10000 Year Clock of the Long Now Foundation.
