Stefan Mischook (of the KillerPHP.com site) has posted a new video tutorial about creating WordPress themes:
I just released a new video course on how to create a Wordpress theme/template from scratch. In these 12 videos, we will take someone with some beginner HTML and CSS skills through the steps needed to build a WordPress template from scratch. The videos use only a collection of freely downloadable tools that are available on Windows and Mac.
The full series will cost about $20 USD for a download or $30 USD to have the DVD shipped out to you. The videos focus on different parts of the process like making top-level navigation, setting up content areas and and creation of a custom homepage.
