Beam is an interactive light sculpture that responds to bodies in motion. When a person approaches, the floor-to-ceiling object turns away, concealing its illuminated side — almost as if shy, wishing to hide something. Through the integration of a sensor and motor, its rotational motion, and therefore its light expression, directly respond to the presence of people, playing with the unexpected: dissolving the traditional hierarchy of objects being “consumed” by the viewer. Instead, it creates an equal encounter. Beam serves as a first technical exploration for a future large-scale installation that investigates how immersive, light-based environments can challenge perception and evoke emotional and psychological responses. Positioned at the intersection of design, art, and psychology, the project explores light as a spatial tool for interaction, self-reflection, and perceptual ambiguity – seeking to transform passive viewing into an active, multisensory experience.
