In 1998, Stéphane Ducret launched his first project, Walls (1998-2000), in which he paints with encaustic (wax) replicas of concrete walls (some of which are inspired by the signature structures of architect Tadao Ando) that he considers a Zen counterpart to the excessive solicitude of images in our lives. A major installation of 12 paintings covering an entire wall was exhibited in 1999 at Camion, Projet d'Art Contemporain, Sierre and was acquired the same year by the Fonds Cantonal d'Art Contemporain (FCAC), Geneva to be permanently installed at the Centre International de Conférences de Genève (CICG).
