Influenced by film, landscape, books, and architecture, Snelling's work references both popular culture and history. A photograph of an actual building can lead to a sculpture of that building which, in turn, is photographed once again. The scale of her work continually grows and shrinks, mutating and distorting each time. The psychological aspects of shelter, home, doors and windows allow her to explore many subjects on another level. The structures are made from various materials, including wood, appropriated images, luminescent wire, small lights, and metal. Some contain sound, water, or motors for movement. The structures are photographed with a large format camera; the insides of the rooms are sometimes lit with flashlights and are then blended into the outside environment using similar camera techniques to those utilized in old films, such as "The Attack of the 50 Foot Woman". Her photographs are featured in the collections of the Museum of Fine Arts in Houston, Texas, de Saisset Museum in Santa Clara, California, the Microsoft Collection in Redmond, Washington and the Progressive Collection in Cleveland, Ohio.
