When the Aura UI first reared its rather ugly head back in November it was unclear what the future of the project was. Now, though, the hardware accelerated window manager and desktop has grown up (at least a little bit) and is being pushed out to owners of Acer and Samsung Chromebooks running on the dev channel. It's becoming clear that Google is prepping to take on the desktop OS market on more familiar ground. The updated UI includes a taskbar, a Launchpad-like launcher and individual overlapping windows, while hardware acceleration allows for those new components to feature slick animations.
