Found a nice overview of the prototype library .

And then found Encytemedia and these articles about graceful degredation:

1. graceful-degredation-with-prototype-rails-part-1
2. graceful-degredation-with-prototype-rails-part-2

Encytemedia is the blog of Justin Palmer, and he has made a great job of customizing Typo.
