Yes and no.  The site engine is based on PostNuke, an open-source PHP– and MySQL-based content management system (CMS).  The version running on xenogere / strange behavior / is heavily modified and customized.  It's also been merged with custom server-side and PHP code for management and other back-end functions.

As for the interface design, I'm afraid I have to take responsibility for that (or claim credit, if you like it).

I'm what you might call "artistically challenged" (as the site indicates).

Still, I did my best to come up with something that I could live with and that was somewhat presentable.  Being that purple is my favorite color, I started with that and worked my way from there.
