The new taskbar is an awesome addition to Windows 7 and comes with new features like jumplists, pin to taskbar etc. Here is a new freeware tool which can center the taskbar icons in Windows 7 which will make the taskbar look like a dock. TaskDock gives the Windows 7 Superbar (Taskbar) a bit more of a “dock” like feel. It will center and re-adjust the Tasks area of the taskbar, centering it, expanding and contracting with new apps and old apps, as they are created and terminated.

The application is portable and does not require any installation. It runs from the system tray and centers the taskbar icons as shown in the image. In case you want to exit the application, you can just close it by right clicking the icon on the system tray and click exit.
