It focuses on the use of computational processes to identify underlying structures and behaviours in Esther Rolinson's drawings. The purpose of this is to define a movement language that can be used to control lights in Rolinson's installation artworks. In this stage the work has a direct relationship to a series of public art works that Rolinson is currently developing in her role as Lead Artist for the building of a new surgical building for Musgrove Park Hospital, Taunton. It informs Rolinson and Clark's shared curiosity about the structures embedded in human actions and sensations. It explores connections between handmade/human and digital processes of construction.
