An anonymous reader quotes a report from Windows Central: Microsoft has made several adjustments to its design language over the last few years, starting with Windows 8 and evolving into what we now know as "Microsoft Design Language 2" or MDL2 in Windows 10. With MDL2 being the current design language used throughout Windows 10, Microsoft has plans to begin using a much more streamlined design language with Redstone 3, codenamed Project NEON. Cassim Ketfi at Numerama.com confirms our information and has heard Project NEON called "basically Metro 2." That designation refers to the first Metro design language (nee Modern) that harkens to Windows Media Center up through Windows Phone 7 and Windows 8. Per our sources, Project NEON has been in the works for over a year internally at Microsoft. It builds upon the design language introduced with Windows 10, with its simple and clean interfaces, but adds some much-needed flair to the UI that the current design language just lacks. Details are still scarce, but we hear some of the new designs in the plans include adding more animations and transitions, with the overall goal of making the UI very fluid and "beautiful" compared to the current, almost static UI that is MDL2. One source familiar with Microsoft's plans described NEON as "Very fluid, lots of motion and nice transitions." Some more information about NEON reveals that it serves as a bridge between holographic and augmented reality (AR) and the desktop environment. It's a "UI that transports across devices" with a UX that maps to the physical world. It uses textures, 3D models, lighting and more.
