Adventures in MVVM -- Ball of Mud vs MVVM

A demo that I added to my MVVM talk is one that compares a “Ball of Mud” application with a componentized MVVM application with the exact same set of features. I do this to contrast a messy, un-testable work of code to a cleanly separated, testable work. The application I chose to write is a Twitter search application in WPF. When you download the code, you will see two folders: “BallOfMud” and “MVVM”.
