Open Source Project Written in Rails 2.0

Hi,

I'm learning Rails 2.0 and would like to see some code that take
advantage of Rails 2.0 features.

I checked blog softwares like typo, chameleon and simplelog, but they
don't seem to use new features in Rails.

I'm looking for a small open source project. Any suggestions?
