About Cairo Dock
It uses Cairo / OpenGL to render graphics (many in correlation with Compiz) with full hardware acceleration. It's fully configurable and fully customisable and can be used as a taskbar too. You can easily add applets in the dock or as a desklet. It is recommended to install the PLUG-INS package (cairo-dock-plug-ins) to have access to more views, dialogs and many plug-ins and applets. Some screen shots are available : http://pics.glx-dock.org This package is the core of Cairo-Dock project.

Open a terminal window and add the following line and copy paste the following line.
sudo apt-get install udo

sudo add-apt-repository ppa:cairo-dock-team/ppa
sudo apt-get update
sudo apt-get install cairo-dock
That’s it Cairo dock is installed. You can start it by going to Applications > Accessories > GLX-Dock (Cairo-Dock withOpenGPL)
