   As I said, I cannot discuss the scientific theory behind the pen, but here is a quote from the literature provided with it: "The P.W.B. ‘X’ Coordinate Pen has been induced with complex messages and when a human writes a message with the pen, the conditions on the object change in a similar way to the events in the ‘double slit’ experiment, in which the essential ingredient is the pure energy form of the photons and electrons which readily interact with the human observer."
