Digital reconstruction in Mixed Reality – of a writing ball using restauration sketches as well as the original patent papers. Created in cooperation with the restaurateur of Friedrich Nietsche’s Writing Ball as well as the “International Malling-Hansen Society”.

  • invented in 1867 by the Danish teacher for deaf-mute people Rasmus Malling-Hansen
  • it was the very first commercially sold Typewriter
  • won prices at various world fairs and was thought to be technically flawless
  • unfortunately, it never became the standard.
  • Instead, the American Remington Typewriters (using the QWERTY Layout) asserted themselves on the world market
  • all in all only around 200 Writing Balls were ever sold

If you like what you see, you’re just the kind of person we’d love to work with.
