Open Source CI projects

[eluser]NateL[/eluser]
I'd like to find some more open source CodeIgniter projects out there.

As a newb to Frameworks, CodeIgniter, OOP, etc. installing and tinkering with an existing piece of software is very educational for me.

I've found Bamboo and am currently looking over the code that Derek has written and I find it incredibly helpful to see how his app is structured and how it functions.

So, aside from Bamboo, any other suggestions? Thank you
