Ruby isn't immune to design patterns.

Some patterns are very trivial in Ruby (Visitor is basically just a  
method that takes a block), and some others don't make as much sense  
in Ruby (Factory isn't nearly as important with classes being objects  
themselves).  Ruby also inspires some new patterns, I believe.  The  
ideas that led to the design patterns and many of the patterns still  
apply to Ruby in some fashion though.
