What a great idea - will give this a bash next week…
If you want a somewhat pretty picture of your DBIC schema (with relationships drawn, of course), install GraphViz, SQL::Translator, and DBICx::Deploy from the CPAN, and then run:
$ dbicdeploy -Ilib MyApp::Schema ~/graphs GraphViz
~/graphs will then contain a .sql file that is actually a png of your schema. Rename it and see your schema in your favorite png viewing application.
