  Visual Systems
  The following visual systems are used as images sources during the opera: four video cameras, a camera for filming the 'lantern', infrared cameras for filming the keyboard player's performance (two cameras), an infrared camera for filming the vocalist inside the 'device', together with two video players, and a video image replay computer with random access. The images from the above sources are modified with both relay and hand held switches and then projected onto the 'screen'. In addition to the above there is also a computer specifically for video delay operations, and a computer that is used to display the sound waves produced by an oscilloscope from the characters voices.
