M.D.R. (Wall of Laughs) is an interactive sculpture by the artist Milène Guermont and was integrated, in 2011, into the exterior walls of the Sainte-Marie de Neuilly's new gymnasium. It is made up of five modules in Craters Concrete (patented invention by Milène Guermont) and Polysensual Concrete. The latter emits sounds of laughter depending on the magnetic field of the person touching it. This work is quickly nicknamed the “laughing wall” by the students.
