Dan Meth: Animator/Illustrator
Dan makes things in many formats and wanted to use Tumblr because it handles different media types so well. This theme uses tags to support the main navigation, and also the subnavigation under Video. He has control over the sidebar links and the top has room to grow as well.
http://danmeth.com is a custom Tumblr theme with specified tag pages as the navigation, in addition to static ‘pages’ that are actually editable posts.
