The code has been available in their public SVN repository for quite some time:

http://src.chromium.org/viewvc/chrome/trunk/src/courgette/

BTW, I've read about 40% of the Chrome code and I have to say it is the single best open-source project I've come to study so far. Incredibly clean code, really shows how much code reviews done properly can benefit project in the long run.

Well, the "cleanliness" is probably because it hasn't been open-source for too long - most of the original work was done by a dedicated team of software engineers most likely operating under fairly strict code guidelines.

As someone who works on a project with a team of dedicated engineers under fairly strict code guidelines including code reviews, I can tell you from experience none of these factors have to do with "code cleanliness" (as ours is not, at least in my opinion).
