Art installation during the Lumière Festival in London, from the 15th to the 21st of January, at King'scross light tunnel.Upperground is a light installation that aims to recall of nature in a place where the user is most removed from it. The lights in the tunnel are connected to the nearest natural park wind conditions and react to them in real time. The goal is to use electric lights to visualise aspects of the natural environment that we are confronted to in our every day lives.Team: Cyril Laurier, Maya Benainous and Joan Sandoval.
