With fiber as his medium, Walker explores wrapped and woven three-dimensional space. He is ceaselessly fascinated by the possibilities posed by a single strand of thread held in ension. As fibrous lines multiply, surfaces emerge. Light reflects from the surfaces and reveals color. Colors become vibrant or fade away. What was transparent grows opaque. Using fibers and light to generate lines, Walker strives to fill and define sculptural volumes. Randy is interested in spatial boundaries and in-between states. Wlaker's work straddles pecariously on several boundaries: solidity and transparency; structural stability and collapse; visibility and invisibility. He creates work that primarily engages oue sense of sight by contemplating how light can define structure, surface, and color.
