I love threads like this where everyone shows off their computers.  After all, its the most important part of the entire windows interface we are talking about - our entire workflow revolves around the taskbar!

Another thing I did was this: I created a PowerPro toolbar that docks to the top of my screen and had it display a clock there.

My monitor is 1920x1080, so it might seem big to some folks.
The reason I'm showing this is because it's another way to have a custom clock.



As you can see in the image, there are other things too: icons that contain menus, a volume-slider (just scroll over it to adjust volume!), and a run box.

PowerPro, if you haven't tried it, is wonderful.

Thanks!
