Is there any way to change the way the phone dialing buttons look on Android?

I am now the proud owner of a Samsung Galaxy S2, and this thing absolutely blows the Apple Iphone out of the water with what it can do. Simply loading SPB Shell 3D onto it makes the Iphone look like Windows 98 by comparison.

HOWEVER, the dialing buttons on the phone app...as in the 1, 2, 3, 4, etc buttons the user presses to call someone...seems a little bland, with their simple gray squares. Is there an app that either replaces the phone app that comes with Android that makes the dialing buttons look more spiffy, or, are there at least skins available that I can change the look on the dialing buttons? What I'm looking for is a round dial face from one of those old style phones, instead of the buttons in a checkerboard pattern, but I'm open to any kewl design I see.

I did a Google search and all I get back are discussions on the physical buttons on the phone chassis itself (menu, home, back, etc). Anything available where I can modify the dialing buttons themselves or am I stuck with the gray squares? Thanks.
