Custom Control Creation (or Why Silverlight Needs a Blink Control)

The last thing I needed today was a distraction from the ASP.NET MVC work i've been doing...but an hour down and I had a control that mostly worked.  I created the simple custom control so that users could specify a Text String, font properties, a blink interval and a blink color.  For example the control can be used like so:

<useless:Blink Text=“Am I Blinking?”
FontSize=“24”
Interval=“0:0:0.25”
BlinkBrush=“Blue”
/>

But then I figured this was a good example of any how to create a simple template-supported control (e.g. supports ControlTemplates) and dependency properties. I will leave the discussion of whether this is a good idea for a control to another blog, but if you want a quick example of a small custom control, grab the code and take a look.  I am open to any suggestions to put it up on CodePlex for the community to elaborate.  The code is here:
