   Revive, the app

   The site in the hand. One rule carries the look: serif type only ever
   shows a mind's own words (the pages, and the words an answer repeats from
   them). Everything the machine writes is set in Inter. Gold is the author,
   violet is the machine, each mind keeps its own colour from the film.
