I have posted my slides from the Ajax experience: Prototype, Ajax Architecture, and Ajax on Rails.

Worthy of note is how the slides are built. If you follow the links you will see that I am using a custom DHTML app. I stated out using S5, but have gradually iterated towards my own bespoke JavaScript and Ruby on Rails powered solution. If you want to view the slides in print, you can now do that, thanks to Austin Ziegler's cool PDF::Writer for Ruby.
