“Agent 57’’ (detail from Alpha augmented reality), by Michael Lewy, in the group show “Augmented Reality — The evolution of a small town,’’ at the Zullo Gallery Center for the Arts, Medfield, Mass., May 11-June 23.

The gallery says the show’s works focus on the past, present and future of the town of Medfield, which was once best known for its big state mental hospital.
