this question is kinda hard to explain

but does anyone know how to put like an image over the frame bars so it looks like one solid site?

i seen a site (i can't remember the site) where the nav bar went from the bottom of the page up to the top and curved right and when you scroll the windows they went behind the image (it was very cool)
i hope someone can help me in the mean time i will look for that site
