Hiya,
Been a while, but I was reading an article,
http://www.boagworld.com/archives/2007/07/emerging_design_trends.html It pointed out a few things that were cool. The two most notables, were a right hand link bar that would migrate to the bottom of the page if the window were to resize to a smaller than 800 pixel width, interesting.
Secondly, right handed navigation was mentioned. Which when I first heard about css, that was my first thought, you can make a right handed nav bar, making it like tabs in a book.
Interesting, but a lot of common sense.
