This session by Laura Scott, Greg Knaddison and Ezra Barnett Gildesgame of pingVision (http://pingv.com) offered a presentation panel on ways to implement web design theming in Drupal, with an overview of how content gets processed from input into what you see on the page, and some specific examples of various ways you can change that presentation of content.

It was a pleasure to be able to help so many people grok theming for Drupal. We currently have the slides we used up at pingVision. Based on the feedback, we'll be building off of this material to create more comprehensive documentation and overview for theming in Drupal.
