Somerville artist Tova Speter uses found wood as a conduit to artistic exploration. The grain serves as her guide on a journey into the lines, shapes, and flow of the composition of the particular piece. In transforming scrap wood into works of art, she conveys the idea that everything has an inherent beauty that will shine through when viewed from a new perspective. Her work is currently on display in the Hunnewell Building Lecture Hall at the Arnold Arboretum in Jamaica Plain, through December 12. For hours and directions, log on to www.arboretum.harvard.edu. The artist will donate a portion of the sales from this exhibition to Spontaneous Celebrations in Jamaica Plain.
