[update] It's been switched over for a while. I'm just editing out the bad links.
It's in no way complete, but I've got enough finished to be able to show it off.
This is the new design. There's a few dummy links in the main menu that link to animations, a gallery and such since I haven't decided how I want to do the Content page, and I haven't fully programmed the main menu links (I can't set custom links yet).
Here is the new design in comparison to the old one.The redesign has been a really ambitious project. The information for everything is stored in a database - content items, content categories, pages (displays anywhere from 0 to all categories), menus, etc. Each page can be set to use a different template set, whether or not comments are linked to, what tag words to filter content through, how many items to display on a page, etc. Categories control what content items are defined as, how they're displayed, what kinds of content can be commented on, etc.
Eventually I'll have the underlying system to a point where I can release the code as an open-source project like PHPBB and WordPress.
