A browser puzzle game where you have to view page source

I played a browser based puzzle game where you had to view the page source to complete the first stage, many a years ago. In later stages the puzzles got pretty complicated, and finding the source code wasn't as easy as right clicking. I wanted to try it again now, to see if I still am the nerd I used to be, and to share it with friends. But I can't find it! Does anyone know which game I am talking about? 
 
And there's a prize: I will follow whoever figures out which game I am talking about.

Have you ever gone to notpron.com... it is rediculous. You have to think incredible outside the box.

" @foggel: Would it possibly be that riddle site http://gob0x.net/ ?
 
Thats the only one i can think of. That or the Donnie Darko site, which was confusing as hell to get through! "
