We have been selling one of our plaster products to Foam Art, which is a Phoenix based comapny that does incredble work with expanded polystyrene. They have been purchasing Tivoli Stone Plaster and Tivoli Stone Classic from us over the last few years to coat and cast over EPS foam.  The photo shown is an example of their work. The product is Tivoli Classic that has been cast by Foam Art with newer casting technology and the finished product looks like honed limestone. Before we installed it we glazed it with Perfetto Glaze to age the pieces.
