This is a bit out there...

Has anyone ever come across a website that lets you go down the Great Wall of China bit by bit? My search engine skills are rubbish...

I know there's a motocross game that has a track where you race the entire thing. From what I remember it's insanely accurate to the real thing. I don't recall the name of the game, though.

Yeah now all I can think of now is if they let google drive the streetview car down it.

There's a google maps bit where you can watch a video of the entire Trans-Siberian Railroad trip... http://www.google.ru/intl/ru/landing/transsib/en.html

Considering the "Great Wall" is actually a complex of dozens of non-interlocking segments spread long distances apart from each other, I doubt there exists such a walk-through; if there is, I'd be curious what order the segments are traced. :-/

It wouldnt be all that interesting, as it is mostly the same along the wall, and most of the historical stuff is at the gates. The only real differances are that for some reason, there are differant translations of the warning signs. Not to mention that most of the fun comes from actualy walking along it.

edit: also, a lot of the time, there will a whole lot of fog/smog that will seriously limit how far can be seen.
