411033 Clickable background ad

I am looking for a small script/code to be able to make the background outside of the framework of a site clickable. Check out the included screenshot - the area marked in red is the framework of the site and should NOT be affected by the background clickable effect. The blue area to each side is the background (Preferably static (not move up and down as you scroll the page); extra bonus if there is a choice in the script/css to scroll the background with the site). When you click on the background (outside the red box), it would be like clicking on a regular link (_blank). The necessity for the background to be a css background is so if someone with a lower res monitor views the site, there would not be a horizontal scroll bar. Sample of what I want is found here: [login to view URL] Click on projection (third from the left) and then the blue rockconcert thumbnail. I am just looking for that effect; simply, a clickable background on the sides of a webpage that does not affect the actual content of the site (background z-index of -9999 or whatever); please take this into consideration when bidding on this project and price your bid accordingly if you want me to accept your bid. I will not go strictly for the lowest bidder, but cost is a factor; and if you can prove a working example of what I am looking for, please include it in your correspondence with your bid.
