How to customize the notification bar?

I don't know even thats possible in case of Xperia mini pro. When I flashed Cyanogen ROM into my Xperia Mini Pro, I was able to customize the notification bar. I mean I was able to change the background color, time color and even was able to show the seconds counter beside the time. Is there any system level application that does the above job on regular(Original) ROM on Xperia Mini Pro ?
