Yep, I design WordPress themes. Check out my site all about making themes for WordPress.
In August 2007, I was the First runner-up in the Sandbox Designs Competition with my entry, Essay.
If you would like to use Essay on your WordPress blog—or anywhere else—it’s available for download at the link above (but you’ll need the Sandbox theme to make it work).
Let me know if you have any problems with it and I’ll do my best to help you out.
