I finally got around to posting my widget for download. You can find the Code2HTML widget by visiting its website. Its home on the web is not much to look at right now. I just wanted to make it available for consumption by the public. I also submitted it to Apple for inclusion in their Widgets collection. As I make enhancements and fix bugs, I will post new versions on the website.
If you want the source for the widget, simply download the package from the website, unzip the package, control-click on the widget, and select Show Package Contents.
