If you missed Cal Evans' webinar (as a part of the php|architect series leading up to CodeWorks 2009) you're in luck! He's posted some of the parts of his presentation on his blog.

Zend Framework is unique in the PHP framework lineup in that it is simple to pull out single pieces and use them independently of the framework itself. This was the premise of the webcast I presented as part of the summer webcast series, hosted by phparchitect and sponsored by Microsoft. It it, I take several pieces of Zend Framework and use them to build a simple little tool. The tools is highly incomplete and only meant to demonstrate technique.

He's posted this sample code and his slides for the presentation for your perusal. The recording of the webcast isn't up yet, but you can check out other webcasts in the series on the Webcasts page on the php|architect site.
