The relatively new Ushasti Gallery (3907 Central NE) in Nob Hill specializes in art with a spiritual bent. The latest exhibit features mandala-like images created by artist Judith Shaw, a graduate of the San Francisco Art Institute, whose work is designed to celebrate feminine spiritual principles through the use of sacred geometries. Shaw's show opens this Friday, June 9, with a reception from 6 to 9 p.m. Stop by to take a gander at this vivid, deceptively simple work. Runs through July 1. 255-1267.
