Retinal Implant Viddy Machine

The Retinal Implant Viddy Machine was a machine that could teach entire subjects within a few minutes. The Doctor found it either on the planet Flogstrune or Mobeli-Four. Two of the Viddy-Reels that played on the machine included Advanced High School Physics and The Galactic Crime-Fighter's Notebook. (COMIC: Doctor Who and the Time Witch)
