An artwork along an everyday route
The city wanted to enliven a facade while the building was under renovation. The work would be encountered during ordinary journeys through Place de Paris, so its interaction began with the movement already present on the street.
Walking past changes the rhythm, density and direction of the waves. A brief pause leaves a trace that gradually dissolves into the wider composition. People can influence the image as they continue through the square.


Light shaped by the facade
Refractiv developed the visual system around the depth and geometry of the glass. Fluid waves move across the surface while small changes in pedestrian activity accumulate within the image.
When the square is quiet, the waves keep moving on their own.

A temporary public presentation
The work was presented for approximately six weeks. Refractiv supervised the installation on site and provided remote troubleshooting during the presentation.
TIJO Studio commissioned the work and led creative production. Brain & More handled project commissioning and coordination within the public programme, and Pro Musik carried out technical installation and site works.
