We've seen the puppeteer  main , and the  main  of the thief. But there are hands that sing, and it is well known that there are many  mécanique  systems which can be used in various ways to make them sing. Usually, each finger takes a note, and all ten sing together, multiple parts of a the two paired hands harmonizing electrically with their own multitude-nature. The rotary keyboard seen here is one attempt at perfection in this field, which has been transformed for use in the  message  passing trade. Pressing a key performs several functions... a note or chord of notes is heard overhead on a speaker, and the ear anticipates the next, hoping for harmony or a hummable phrase; at that moment, a  lettre  is pressed on the  surface  of a piece of  papier , deep inside the  machine . Also at the same time, in another  pièce   connecté  to this one by a system of levers, a hard metal stamp presses an image of that same  lettre  onto the  surface  of a soft plate of metal; and by  parallèle  machinery attached to the plate for alternate purpose, an electrical impulse is transmitted into the  air , which allows the  lettre  to travel at the speed of  lumière , but weak as darkness, past the  lune  and out to the thin ether between the  étoiles . By such multiple and expensive means, the telegraph company seeks to conjoin the operations of  transmission  and archive storage of all paid messages sent through its' machinery. Between music and lead type,  papier  and  radio , somehow the  message  will get to someone, either in  espace  or across time.     L'ironie de la chose était Spiralum, elle-même, était une inventrice en électronique, qui rêvait de développer un instrument capable de transmettre des images mouvantes par téléphonie.
