During Christmas period, the Paris City hall decided to install various animations in several places of the capitale. Thus, "les berges de Seine" (riversides of Paris) have been decorated by the design agence Light Lab and the technical specialist Lumière et Son. This installation was a 3D volume, made up of 108 tubes LT-200 of 2m (9 x 12), monitored by a Madrix system. The sophisticated effects represents the "mood" of the city. This concept can be seen until the end of january between the Concorde bridge and "passerelle Solférino" (Solférino Bridge), on the left riverside.
