Inspired by James Turrell’s Ganzfeld and Skyspace installations, Luminous Portal evokes the same sense of spatial ambiguity on a smaller scale. By concealing its lighting mechanism within a meticulously designed 3D-printed shell, the luminaire eliminates perceptual depth, immersing viewers in two light-filled chambers. An Arduino-driven lighting system subtly shifts the outer chamber’s color, dynamically recontextualizing the inner chamber while abstracting the luminaire’s physical presence.
