Kate Shaw's 2007 exhibition Mirror Matter at the Nellie Castan Gallery in Melbourne delved into the interplay between perception and reality through her signature technique of poured acrylic landscapes. Shaw's exploration of natural forms rendered in surreal, mirrored compositions. Her works often feature vibrant, kaleidoscopic terrains that challenge the viewer's understanding of the natural world, suggesting alternate realities or dimensions.

The term "mirror matter" originates from theoretical physics, referring to a hypothetical counterpart to ordinary matter, potentially existing in a parallel universe and interacting with our world primarily through gravity. In the context of Shaw's exhibition, this concept metaphorically resonates with her artistic approach—creating landscapes that are both familiar and otherworldly, reflecting a parallel version of nature that prompts viewers to question their perceptions. By intertwining scientific theory with artistic expression, Shaw's Mirror Matter invites contemplation on the nature of reality and the unseen forces that shape our environment.
