We've created a handful of open source code libraries to power our website and animated media. Nothing too fancy, but they solved a need for us and, hey, they might help you out too. You're free to use these libraries in your projects. If you find them useful, we'd love to hear about it (firstname.lastname@example.org), and of course, pull requests are welcome.
Building LunchBox Sessions would have been much more difficult without the help of these open source resources. We are indebted to their authors and contributors.
