This is just a heads up to anyone using my 3D math library "kazmath". Kazmath was originally written for Beginning OpenGL Game Programming II but has been continually improved and updated since then. It's now a fairly large library being used by quite a few people. I've recently moved development of kazmath completely from Launchpad over to GitHub. You can find the repository here: https://github.com/Kazade/kazmath
Kazmath is BSD licensed so free to use in both open and closed projects. Feel free to report bugs, and if you improve the library, just send me a pull request on GitHub :)
