Request: Crowd open source walkthrough (Video + shared screen)?

It would be cool if some HN reader could introduce the crowd to their open source project. Walk through the source code (with focus on the "meat"), architecture, design patterns used, modules etc, so that anyone interested with enough programming experience could dig in sooner.

It could be done over Google Hangouts or Skype or similar with shared web browser view. I would probably consider pay a little for such an event since it would be awesome.

- Open source code walkthrough at e.g. Github - Demo with modification and compilation in an IDE (or in a browser) - Discussions about design choices - Q&A

Anyone interested?
