Does Elon Musk get any sleep? I don't think so. The SpaceX founder has tweeted that he has invented a new way of creating rocket parts, by simply using hand gestures and a laser printer. He has posted a video showing this off, which is an incredible achievement.
Musk explains in the video above: "Right now we interact with computers in a very unnatural, 2D way. And we try to create these 3D objects using a variety of 2D tools. And it just doesn't feel natural - it doesn't feel normal, the way you should do things." Musk continues, demonstrating how he combined a bunch of technologies, including Oculus Rift, Leap Motion 3D controllers and holograms, in order to create a way to engineer a rocket engine, all without physically touching it.
Musk says that this system is "going to revolutionize design and manufacturing in the 21st century." The technology shown off by Musk is quite incredible, as it's all in early stages right now.
