Microsoft Hololens is that company's take on wearable computing and augmented vision, and Microsoft put on an amazing demo Thursday at Build 2015. Hololens allows you to impose virtual reality onto your vision of the real world through the use of glasses. It's early days for this technology yet, but the demonstration was impressive. Highlights of the demo include creating a video that follows the user around and being able to place apps on a wall so that you see them whenever you enter a particular virtual room. There is also a virtual menu that is SciFi brought to life (if you can ignore how slow it was and how careful he had to be to manipulate it—early days, like I said). On the other hand, watch the very unnatural and awkward way the demonstrator walks around without moving his head or neck. Despite such armchair nitpicks, it's a remarkable demonstration.
