Voodoo Doll App

John invented an app. The app sent out neural binders to a person. All he had to do was get within 30 yards of the target to make the link.

The app would then pull up an image of the person, and the image would change as the target moved. For example, if the target was sitting, the image was sitting.

The app would allow John to do things with the target just like an ordinary voodoo doll: tickle, prick, raise an arm, close the mouth, feel heat or cold, etc, and the target would have no idea what was going on. The app could only change how the target moved or what the target felt.
