On the InsicDesigns blog there's a new tutorial on using the MiMViC framework

MiMViC is a modular and lightweight PHP 5.3+ Web application framework designed to help build dynamic and robust Web sites. It's theory is based on minimal and framework emphasizes on only core glue for your complex PHP web sites. Today I will show you how to create a shout-box using the MiMViC framework. It won't take you more than 15 mins to get the job done and have friendly URLs as well.

Sample code for the "shoutbox" is included. Their example shows an Apache setup and a MySQL backend (complete with namespace-enabled code). A simple form to take in a "shout" works directly with the framework to save the information quickly and easily.
