In 1995, an American inventor, John Walter, developed a device that he calls a ‘true mirror’, which does not reverse images in the way normal mirrors do. It consists of two perpendicular mirrors in a box, the second mirror acting to undo the reversal of the first. Walter reports that whilst some people don’t notice any difference in their reflection, others either loved or hated their un-reversed reflection.
