The Perceptions series is relatively new in John's work. Some are anamorphic, while some are kinetic, but the constant is the use of assemblage to create multiple perceptions in a sculpture, or to evoke thought and contemplation.
The Portals series is John's longest running series. It is constantly evolving, but the themes and thesis stay constant. Portals represents John's interpretation of the universe and its complexities. Multiple planes of existence, multiple ways to view them or experience them and how choice influences our reality.
