An Animated Taskbar
Introduced with Mac OS X, the Dock's icons are slightly animated. As the cursor is moved along the Dock, the icons are magnified creating a rippling effect. The Dock can be located at the sides or bottom of the screen and can be set to hide (autohide). Icon size and their amount of magnification can also be adjusted. See Pin to taskbar
