Reminds me that one of the "guns" I designed has actually be produced by the US military in RL. Quite a while back I had an idea for a small shotgun-shell-sized drone to be fired from an air rifle. Once the "drone" got to a certain hieght, a small balloon would inflate and the drone would float lense down in the air. A small transmitter would broadcast the video to a reciever on the ground.
Now it turns out the US Military has developed a bulky version of the same thing, only with a parachute instead of a balloon. And can you believe those fraggers haven't even given me one royalty check??
