Rocket Dock is a free Applications Launcher for your Desktop. It is kind of like the Windows Taskbar quick launch bar in Windows. However, Rocket Dock is more customizable. You can download new themes, icons, and widgets which run in your Dock. You can also minimize windows to your dock. If you own Vista, or above you can even preview thumbnails of minimize windows on the dock. It works great on slower computer. The dock looks similar to the dock on OS X , Ubuntu, and Linux distro docks like gOS.
