Saturday evening artists Ken Vincent and Traeger di Pietro set up easel, light, camera and projector at Lighthouse Beach in Edgartown. At nightfall a new mixed media painting was created. Brush strokes projected onto the Edgartown Lighthouse. The end result; a painting of President and First Lady Obama. The finished painting is for sale at the Granary Gallery. Proceeds will benefit National Breast Cancer Foundation and the Martha's Vineyard Public Charter School art program.
