Desktop Icon for Application

We need a desktop icon for our scheduling application. Icon should look good in XP and in Vista. Preferably it should be designed according to the same style and specs as icons are in Vista. My idea is this: A computer screen with some kind of calendar on it. A clock is coming out of the monitor, or is overlaid partially over part of the monitor. In other words, some combination of a clock and a calendar. It doesn;t need to be exactly like that, but should look nice, professional and cool. We'll base our decision on what you can show us you;ve done previously. Thank you
