So I have added to the mix another passion of mine - CodeDom and therefore present:
The CodeDom Visualizer
The Visualizer will use all of the languages you have defined on your computer (using machine.config) to represent the unit, namespace, type, member, statement or expression.
You can download from here:
To install, simply drag the binaries to %DEVPATH%\Common7\Packages\Debugger\Visualizers.
[Update: Haibo Luo has a really cool visualizer for dynamic methods. I have a feeling I'll need it some day... :)]
