Cairo-Dock is an animated application launch bar for the desktop, comparable to the dock in Mac OS X or Rocket Dock (for Windows). Now, you can use Cairo-Dock with OpenGL (to use your graphic card!).
It is compatible with Compiz-Fusion, Beryl, Compiz and Xcompmgr, but it can also run without a composite manager (using fake transparency). Cairo-Dock can run under GNOME, KDE and XFCE.
