Marigold is a component based rigging solution inspired by Unity3D. Though it will remain a work in progress for the foreseeable future, I decided to put the source code online.
This is a project I work on every day of the week and check in updates often. Keep this in mind if you do download the code.
I also blog a lot about the state of the project and my thought processes. These posts are in the category Marigold.
