I just posted the latest iteration of my Rails presentation and its 
available for download from here:

   http://rubyforge.org/docman/?group_id=251

Look for the entry:

   Rails Presentation 2005-06 [ 2005.06-Rails-Presentation.zip ]
   Description: Curt Hibbs' Rails presentation to the
                St. Louis Java Users Group

It includes a video that goes through the entire development process for 
the cookbook application in part 1 of Rolling with Ruby on Rails at:

   http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html

Feel free to use it any way you like.

If you've done any Ruby or Rails presentations yourself, please consider 
  posting them to the "Why Ruby" project on RubyForge.
