"The visible is only a vibrating membrane of the invisible." The Visible and the Invisible, Maurice Merleau-Ponty, 1964 Fréquences is a luminous score inscribed in the very matter of a building. Deployed at the scale of an urban façade, it makes of the visible a porous membrane. Each light module is a node of vibration within a larger network, whose pulsations the visitor moving through the city perceives without ever grasping the whole. The work rests on a pre-written score — a defined grammar of sequences and intervals — but its unfolding reintroduces chance each time: the ambient light, the flow of passers-by, the wandering attention of the gaze redefine the protocol and put its legibility back into play. Fréquences behaves like a vibrational field, resonating with the viewer's perceptual space. Light traces a presence and brings architecture into resonance with the flow of the city. The façade becomes here a sensitive interface between interior and exterior. In 60 minutes (one complete cycle), the work materialises the passing of time and our relationship to the verticality of the urban landscape: an invitation to inhabit space and time differently.
