In RARE PLUS, Matthew McGuinness presents a selection of mixed media collages and soap sculptures that document his all-encompassing art/lifestyle projects in an exhibition entitled Rudolf: A Salutary Pipeline. The title refers to Rudolf Diesel, the inventor of the engine that bears his name. For McGuinness, Diesel and his invention are a metaphor for one of the biggest environmental, economic, and political crises of our time. Originally designed to run on vegetable and seed oils to enable craftsmen, artisans, and farmers to compete with large industries, the engine has gone through a recent renaissance as underground, do-it-yourselfers have reconfigured it to draw attention to a variety of current issues and causes.
