With Google's fleet of Chromebooks making their way to market, Mozilla Labs has decided to release a similarly browser-based desktop interface, known as the Webian Shell. As of now, the prototype app consists of a screen-encompassing web browser, which essentially replaces your desktop interface. There's an address bar running across the top of the screen, a clock in the bottom right corner, and a tab button for all your web apps. Developed as part of the company's Mozilla Chromeless project, the tool was written entirely in HTML, CSS and JavaScript and, unlike Chrome OS, is designed to run on top of existing operating systems, rather than replace them. For now, the Shell is still in an early phase of development, looks pretty spartan and can't control a system's hardware. Mozilla, however, says it has plans to incorporate multiple home screens, split screen views and an on-screen keyboard, among other features. Windows, Linux and Mac OS X users can download the Shell now, from the source link. Otherwise, you can just head past the break to see a brief demo video.
