"There's no point in making a mistake unless you understand the mistake so that you donít make it again."
- Alfred Bester

Magnetic Eyes  
  A device that permits remote monitoring of people or other objects.  

"`Magnetic eyes' are of great use to miners and Civil engineers. These instruments are something like the mariner's compass, with the sensitiveness enormously increased by galvanic currents. The `eye,' as it were, sees what substances are underground, and at what distances. It also shows how many people are in an adjoining room -- through the magnetic properties of the iron in their blood whether they are moving, and in what directions and at what speed they go. In connection with the phonograph and concealed by draperies, it is useful to detectives, who, through a registering attachment, can obtain a record of everything said and done.
