This cannon solved the amateur radioman’s problem of setting up long antenna’s over top of trees. The old method of a slingshot or bow & arrow were too oldschool for the inventor.
One of the coolest features is the augmented reality scope. The inventor rigged up his HTC Desire Z android smart phone up top, and installed GeoCam (an augmented reality aiming app).

I briefly installed the GeoCam app on my Motorola XOOM, and in the limited amount of time I played around with it, it seemed pretty cool. Maybe if I’m feeling adventurous someday i’ll mount it on a gun and see what kind of groups I can get.
