I want to work for free in a nodejs web project

I have around 6 yr experience. I worked in lot of technology on and off. I am confident to develop a web app end to end. But not very focussed so far. I want to work with some one preferably a techie like me on some nodejs project. I mean we can brainstorm on some idea, I have few and sure that you also have some. We will pick one and go after it. I played with Ruby on Rails a bit. Now technically I want to focus on NodeJS, no specific reason but feel like it.

Any body interested? Or can share some tip with me how to find some one with similar interest.
