This unnamed German gent loves paper airplanes so much that he started a website, Papierfliegerei ("paper aviation"), dedicated to spreading awareness of their history, manufacturing techniques, competitions and more. He also designed and built a machinegun that not only fires paper airplanes—but actually makes them. Which is to say, you load it up with unfolded sheets of A6 paper, the gun turns them into airplanes and then continuously fires them out of the business end:
Interestingly, a minority of the gun's contents are off-the-shelf parts; the rest of it he had 3D printed by Fabberhouse, a Germany-based output house. If that guy in Texas was disseminating designs for 3D-printed guns like this, the news coverage would be considerably different.
