In terms of the fetishization of ancient relics: In the photo of RMS, his "halo" is a disk platter (looks like an RP06 platter but likely was from some "winchester" drive of the 80s). The diameter is about 360 mm (14 metric inches), because the entire drive was 19 inches wide to go into a rack. Those large drives could store an enormous amount of data: sometimes as much as a megabyte per platter!
