The Razr HD default Clock "triple circle thing" is a widget. Widgets can be removed and replaced with other clock widgets.
Clocks are also available in the form of Live Wallpapers, these too can replace the default clock.
Another easy way to change the look of any phones interface is to download and use another Launcher.

Hope this helps.
Push and hold the Triple Circle Thing (henceforth called the TCT) and you will be able to drag it to the red x that appears and delete it.
We would be happy to help you customize your phone.
