Suspended on a rooftop we see either a transmitter or a receiver for such a back of the  tête   Mirroir , which has the potential of turning something previously difficult, such as the  transmission  of the  mort , into something available to each and every household, and indeed for every person... creating a need as common and necessary as grooming.     Le récepteur changeait le son en images mobiles des morts, qui pouvaient flotter, libres et vivants, dans l'air.
