A corner cube (the corner of a box, with all three faces at right angles to each other is called a retro reflector, because light from any direction (within the scope of the corner cube) is reflected back at the originator. This was found to be true for shotgun pellets when a curious shooter saw a corner
cube on a pole that was meant for communications, and fired on it. Naturally, the shot returned to the shooter with minor injury resulting. Now imagine an array of these either worn as a vest, or placed throughout high crime rate neighborhoods; perhaps the random shooter would be more cautious if there were a chance of the target shooting directly back.

You could even call it the "Right back at cha' vest". Could you not? |

That "prior art" with the little U shaped tubes is the wrong way to do this; a corner cube is effecticely equivalent to millions of "u-tubes" since it can handle projectiles from a large angular acceptance (technically, pi/4 steradian).
But Back ach-ya is definitely the overall effect. How about putting a Bambi exterior "skin" over the array and place it in the middle of the woods during hunting season? |

Wouldn't work with a bullet, sorry. |

Actually it will, that is the origin of this idea, a fellow was injured firing at a corner cube. |
