I have a client that loves WordPress and I have been doing some preliminary research to see if the website they want is possible in WordPress.
What they want is a feature marquee that is dynamically populated with stories assigned to the "feature" category. Now normally this wouldn't be an issue and it seems pretty trivial but this is where the shenanigan begin.
They want a feature marquee section like the Top Stories section you see on Bungie.net or Tomshardware.com. I.E. the top four or five stories dynamically rotate an when you rollover one of them you get that story's short summary and title and associated image.
