Invisible Peace Pole
A column made of sound.
Recordings of "May Peace Prevail on Earth" in various languges play when a motion detector senses someone in the invisible peace pole.
It's called HyperSonic Sound (HSS). It creates a narrow column of sound that has little spillover. People five feet away cannot hear it. But within the column it as like wearing a headset even though the sound source might be 200 feet away. It can sound as though someone is whispering in your ear or like a train is roaring past while people five feet away hear nothing.
Picture one small spot on the floor in a lobby or to the side of an entrance. Perhaps just the word "Peace" on the floor. If you stand there, the heavens speak.
Two sizes available. The small one is $1999.00 not including mounting brackets, which are usually under $100 and the ipod or other device to hold the recordings.
The large one is around $3000.00, not including ipod and brackets.
The recordings are free.
