French interdisciplinary designer and researcher Coralie Gourguechon revisits her Wall Radio (2013) installation for Art-o-rama Marseille. Made from a single copper wire configured into a coil with nails, the rudimentary circuit acts as a powerless radio receiver that picks up AM frequencies visitors can tune into via a crystal earpiece. Gourguechon’s installation is modelled after makeshift foxhole radios that U.S. soldiers improvised during World War II.
