One detached, one accusatory, doll-like and dark, masculine and feminine at the same time, these have to be among the stranger mermaids out there. Conceived of by Aurie Ramirez, an artist working at Oakland’s Creative Growth Art Center, a studio program for mentally, physically and developmentally disabled adult artists, these girlish ladies stick in the mind for their sheer weirdness. (‘Creative Growth’ is at Rachel Uffner Gallery through August 10th.)
