A ghost board is like when a person can't communicate by normal means.What the ghost board does is it has temperature sensitive point's on the board.That represents the alphabet. You ask a question.and hope the spirit answers back by activating the sensors. The sensor's will softly make a tone that represents the letter's or number's.But not light as light is disturbing to the spirit.It would seem.
The sensors could be relayed to a cell phone.As full sentences or in a stop gap sequence.
It will likely work best with the spirit's of children.By setting up a game for them.A kind of Singapore effect if you will.
I got the idea from an episode of Taps in which the spirit of a eight year old turned a flashlight on and off .In response to question's.
This a follow up to my question on the body challenge posting.
