I just did a quick search for AdSense Backgrounds and found one of the sites selling this.

It's just a frame or border around the ad, not an actual background, showing the ad block within a notebook, in a calendar etc. and actually they look pretty good.

They appear to be TOS compliant, but they are pushing the envelope as far as 'undue attention' goes. I won't be using them myself...
