Dilworth often encases natural objects he has found within his sculptures. The solid remains of animals and birds, beautiful in their own right, impart an energy and life to his sculpture. Even when completely enclosed, like the heart in a living body or the engine in a static vehicle, they empower the sculpture in both conceptual and symbolic ways. Dilworth says: 'I want to retrieve that moment of understanding, not by describing but by making. Of course I’ll fail, but in that chemistry of making another moment will appear. These objects are drawn from an internal landscape of shifting sands, connections are constantly being discovered.'
