From Ruth Piper herself. I work under the overall title of ‘existential diagrams’. Influenced by emotional narrative and psychological undercurrents I borrow the format of the diagram, sometimes referencing architectural forms or road maps using opaque block colours, inventing a kind of cognitive cartography to build up images. I use simplified abstract objects to construct a narrative in the plan view. Experience, sensation, time and memory become gradually compressed into the format of a colour coded map that can function as a portrait, landscape or simple diagram suggestive of the complexity of human relationships. I am particularly interested in the reciprocal energy exchange that occurs between the viewer and the artwork.
