Tony Smith began his career through Minimalism, working with architecture and painting. His work soon turned to monolithic, system-based sculpture that was based on intuition. Throughout his work is an interest in repetition and multiplication of the visual and physical world.
Smith was not constrained by the boundaries of medium, which was seen through his transition from architecture to art and realising his creative principles. The development of his works throughout the career can be traced back to the natural and human universes of repetition and multiplication. There is a presence of his works, no matter the compositional technique used nor the angles of the repeating forms.
