I searched the archive and found that this particular Pale Fire website hadn't been posted yet. It is an attempt to map the chronology of the main characters of Pale Fire to Google Earth and thus display the movement of the key characters in the novel:
It is certainly an interesting endeavor (the first Google Maps/Earth and Nabokov mash-up as far as I know - Road map of Humbert Humbert and Lolita's motel journey anyone?) but I can't help but wonder how the real-world locations relate to the fictional places.
