"Holding the Light for You," by Somerville artist Melissa Shaak, is a series of seven sculptural figures that took a dare and stepped out of their paintings into space and time. Each raises a torch, or scepter, holding the light, signaling and leading the way. The invitation inherent in the work is to catch and take hold of the creative impulses that come our way. Two of the figures are currently along the bike path near Davis Square, Somerville. www.melissashaak.net
