Draft of Bioinformatics Graphic

I've been working on a graphic for a preview story for the Bioinformatics conference, and have attached a copy of our current front page with it inserted to give everyone a chance to see what we are aiming at.

Shova made the very good point that anything added cant result in a graphic horrorshow, so in this case Ive gone for a fairly harmonious color scheme. MIT changes their entire front page color scheme based on theday's new graphic! Something to think of for down the track, but in the meantime we can:
(1) try to make the graphic fit the existing scheme
(2) if any graphic cant be shoehorned into existing scheme, perhaps change the color of a few features (eg "About Us" etc boxes) when needed (thanks Shova).
All feedback is good!
