I realy like the background pattern. It is really neat, elegant and subtle. Not too noticable, yet it gives the site depth. I enhanced it a little bit to make it lighter and added contrast so the detail is more vissible. Lots can be done with this, add a tint of color, shrink it, fade it out more. If you want to donload it right-click on the left side of the pattern below and save it to your computer.
