A white bird feather is connected to a small motor and suspended at the center of the circular elevator of the New Cathedral in Linz. Upon entering the lift, the feather initially remains still. Only through the presence of visitors is movement triggered via sensors connected to an Arduino system. The feather begins to rotate slowly, gradually increasing in speed, extending into the architectural space and brushing against the bodies of the passengers. The elevator, typically perceived as a purely functional transit space, is reconfigured through the fragile and unpredictable motion of the feather. Movement, spatial confinement, and bodily proximity reshape perceptions of control, safety, and orientation. The work unfolds through the interaction of site, technical activation, and situational encounter.
