Periwinkle Shaft (1979–80), a monumental work commissioned by the Arts in Public Places Program of the National Endowment for the Arts for the Children’s Hospital Medical Center in Washington, D.C., extends Rauschenberg’s dialogue between art, technology, and ecology. Composed of solvent transfers, layered fabrics, mirrored Plexiglas, and electric light, the five-panel installation embodies his belief that art could merge with the rhythms of daily life. The reflective and translucent surfaces invite viewers into an immersive experience that feels alive—animated by movement, light, and material transformation.
