Here's 12 minutes of gameplay footage of Star Citizen, a space flight simulator video game that will let you live in a parallel universe. Not only pilot a spaceship, but have a living avatar there. And with Oculus Rift support, it will be a total alternate universe experience. It looks absolutely fantastic.
To show off their microscale 3D printers, Nanoscribe printed this model of a Wing Commander Hellcat. It took about 50 seconds to print and the dimensions are 125µm x 81µm x 26.8µm, with its length roughly the diameter of a human hair. Now we can film space battles under an electron microscope.
