Whats that website called with the big online puzzle?

hey guys

quite a few months ago i went on a website when i was bored in college and it was like a massive puzzle. it didn't have puzzle games on it, it was just like one huge puzzle the website its self and im pretty sure it begins with the letter C



The website has many different levels and at some stages you have to find out how to get to the next level by looking in the HTML script and it gives you small clues on how to get to the next level. at some stage you have to convert foreighn letters into english ones and use that to get to the next level by typing it into a prompt which apears.



Ino im rambeling on a bit but if anyone knows the name please tell me its doing my effing head in lol
