I had some time today so I decided to check out Linux Deepin 12.12. Linux Deepin is a Chinese distribution based on Ubuntu 13.04. It comes with its own desktop environment called Deepin Desktop Environment (DDE) and its own set of default applications.
The look & feel of Deepin is very similar to the Window 7 desktop with transparency, shadows and glass effects. While the Windows 7 theme may not appeal to all Linux users, the desktop is extremely well-polished, and one of the prettiest desktops that I have seen since I came across the elementary desktop a few years ago. If you are someone who enjoys trying out new Linux distros then Deepin is something that you don't want to miss.
The DDE desktop is based on Compiz. There's a compiz-based dock at the bottom of the screen which acts as the taskbar. Moving the mouse over an aplication icon shows a preview window similar to the Windows 7 taskbar. The desktop supports icon grouping. Dragging one icon over another will create an icon group.
