The Open Source Recruitment Thread

Practically everybody should be contributing to open source; it's good for your career, and your skills. So what are some of the projects, libraries, etc. you're working on that could use some help. Post some information about them so fellow HNers can start contributing.

Just tell us: What language it's in, what it's called, and where we can find it. What it does. What you'd like to do and what you need help with.
