PHP and Codeigniter in action

So I've been reading a lot of the Codeigniter user manual, and while it's very intuitive and helpful, I learn best by doing and seeing. Are there 开发者_StackOverflowsome good example sites out there with source that I can browse through and see how it all comes together?

Thanks!
