Ruby on Rails Screen Casts (rated R :) )

I came across during my never-ending quest for Rails and Ruby related websites, in this cute site (re-design, fast) at Ruby Plus.
They composed over 90 (to this day) screen casts about ruby and rails, including some Rails 2.0 roundups, Ruby metaprogramming and so on.

use it, bookmark it, watch it. (and get the feed too :) ).
