The '''''' (from German: 'Electrical Quick-Viewer') or Electrotachyscope is an early motion picture system developed by chronophotographer Ottomar Anschütz between 1886 and 1894. He made at least seven different versions of the machine, including a projector, a peep-box viewer and several versions with illuminated glass photographs on a rotating wheel viewed on a wide milk glass screen by up to seven people at the same time.
