I did a quick search and didn't see the site mentioned so hopefully this isn't a repost.
I stumbled upon this site while looking to see if anyone has ever cataloged all the graffiti on the Nordschleife. While this place doesn't have anything like that, it's got some cool stuff, including a satellite photo of the Ring with bend names that can be used as a wallpaper
Check out the Insurance link on the site if you want to see what used to be a beautiful black F360
