Looking for plug and play rails sample apps

As I learn rails, one thing I'd really like would be access to
complete rails applications (sqlite3-based, please) so that I can poke
around in their code and see what other people do. Could any of the
readers point out such apps that might be available for download?

Many thanks,

There are a number of apps out there in various states of development.
You may find something useful.
