When designing an application around Model-View-Controller (MVC), what is in your toolbox?

Question

There are a lot of great explanations for what the Model-View-Controller design pattern is, but I am having trouble finding good resources showing how to use it in practice.

So, when you are starting a new application (doesn't matter what it is), what is in your toolbox?

For example, it was suggested that using UML collaboration diagrams ( http://www.objectmentor.com/resources/articles/umlCollaborationDiagrams.pdf ) can be useful when designing an application around MVC, although, I am not certain exactly how or why this might be the case...?

So, what is in your toolbox for MVC?
