Build basic CRUD application in Rails using Event Sourcing

I was recently reading a blog post titled Event Sourcing Made Simple ([login to view URL]) that described a different approach to building Rails applications that they were using at Kickstarter. They put together a very small (couple of hundred lines) framework to implement Event Sourcing as they are doing it in their own applications which they shared here: [login to view URL] I want to build out a very simple demo project that follows their code and methodology that has the full CRUD functionality for a Post resource which just has a title and a content. It should also have a User associated with the post so that I can see how the metadata is handled within the events as per the blog post examples. I just want to use this project as a way of teaching myself how this would work in reality. I had some problems in trying to follow the blog post myself because I am not a very advanced Rails coder.
