Géologie des flux

As part of an unprecedented partnership between Lyon Parc Auto and the Mirage Festival, Chevalvert studio and designer Martial Geoffre-Rouland were asked to create an interactive and luminous installation called “Geology of Flux”.

The works presented offer a sensitive approach to all the data related to the activity of a car park, while capturing the flow of passers-by.
