Here are some links to public source code for which George Carrette is the exclusive or predominant author, or where it can be revealed as obvious what modules I created, along with some commentary on why it might be interesting. This dual criteria of open source and predominant authorship is somewhat limiting, and tends to eliminate large scale engineering efforts that tend to have a very different style. More pointers are available starting at http://alum.mit.edu/www/gjc/.
