Introduction
This article presents a digital clock written using C# .Net 3.5 and Windows Presentation Foundation (WPF), with a version supporting styling using the RibbonStyleHandler from the Ribbon Control Library (and hence allowing styling consistent with RibbonWindow applications).
Using the Code
This is VERY simple, to create a new clock window, make a new instance of DigitalClockWindow! To add a control to an existing window, use DigitalClockControl.
About the Code
The DigitalClock class is comprised of DigitalClockDots and DigitalClockElement. The DigitalClockDots class is a UIElement representing two dots to separate hours from minutes from seconds. DigitalClockElement represents the following states: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Hence the DigitalClock is a Grid of DigitalClockElement DigitalClockElement DigitalClockDots DigitalClockElement DigitalClockElement DigitalClockDots DigitalClockElement DigitalClockElement.
The DigitalClockControl and DigitalClockWindow classes contain a thread for updating the clock when AutoUpdate is set to true, otherwise the clock may be updated via the .CurrentTime property of DigitalClockControl.
DigitalClockControl contains three properties for styling, DigitBrush the Brush used to render the digits (0 to 9), DotBrush the Brush used to render the separating dots, and ClockBackground the background of the clock. DigitalClockDots contains a single property RenderBrush for setting the brush used to render the dots. DigitalClockElement contains a similar property RenderBrush for setting the brush used to render the graphic components. Furthermore it also contains a Value property for setting the value to display (in the range 0 to 9).
Ribbon Styled Clock
In version 1.0.0.1 RibbonClockControl and RibbonClockWindow have been added which inherit from DigitalClockControl and DigitalControlWindow respectively; they add automatic styling based on the RibbonStyleChanged event, and can be seen in use in the CIRIP project (a Computational Intelligent Railway Intervention Planner).

A new version has been released which significantly improves the code quality and ease of use! As requested the control resizes too now.

Is that the correct spelling?
I like a lot of programmers also suffer the lack of logic in the English language.
Great control btw 
Cheers

You're correct, i'm off to change it now.
It's odd that the code project submission wizard doesn't have a built in spell checker.
Ps. I want intellisence for Word

When I type Alt-F4 to close the clock, the thread isn't terminated, so it remains in the process list. This also prevents further recompilation of the code until the process is terminated. I'm surprised you didn't discover that yourself. 
How do I change the skin? Your article shows three skins, but the program only shows the first one.
How do I modify the window so it's sizable? I tried a few things but the code would subsequently crash.
Thanks!

Firstly thank you for the comments.

In the context i'm using it's not a problem as the thread gets registered elsewhere and gets closed there. A slight oversight which I will correct when I get a moment.

Take a look at the Ribbon Control library in the referances section. The styling of the control is done by RibbonStyleHandler. Calling RibbonStyleHander.restyle(RibbonStyle.Blue|Green|Gray|Black) will give you some options. Also take a look at RibbonStyleConfigWindow which is currently being developed and finalised. In the next version i'm restructing the code significantlly better which will give better access to manual styling.

It's not implemented yet is the simple answer. Off the top of my head though I know you can perform some render transforms, so that would perhaps be the quick fix until I make to control more sizable (which I will endevour to add in the next release also).

Ps. OMG how much time do you have!?! 124 articles, it's taken me ages just to produce 15. There is some good stuff in there though for sure; personal thanks as I've used your work in the past.

LOL! Well, where there's a will...
A lot of the articles based on actual things I've had to develop, so there is a "killing two birds with one stone" effect.

Both of those articles are based on an exhibit on fractals that, I believe, is still running (after 17 years, OMG) here[^] in San Diego CA.
