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,
Ken
