While the Maine-based artist Elizabeth Atterbury has done amazing things with just simple shapes cut into paper and steel, lately she's been getting a wee bit more ambitious — building a 3-by-4-foot sandbox in her studio and photographing compositions she's raked into it, or using a bandsaw to carve grill bricks into arcs and zigzags then documenting the crumbly results. Aside from photography — which she studied in school — she also exhibits sculptures in clay and painted wood. You can see them in person now through May 10 at Colby College Art Museum in Waterville, Maine, or pick up a copy of Atterbury's 2013 book with Bodega gallery, "In the Middle, an Oasis."
