Looking for sample application

[eluser]cmh24[/eluser]
Hey everyone,
I am eager to dive into CodeIgniter, watched the first halve of the Nettuts video series and looked at some other CI resources.
But I have problems to do the next step, so I am looking for a sample application like a blog or something like this.
I found DBlog ( www.davidbehler.com] which is to complicated for me to understand, also BambooInvoice is far beyond my understanding.

So far I built a basic blog with login form, pagination, form validation and comments.

Thanks for your help.

Greetings from Germany!
