I liked the one I posted with my writeup of making png.rb faster with  
RubyInline since Dominik (sp?) gained similar speedups with pure- 
ruby.  I think the pure-ruby speed-up ended up within an order of  
magnitude of the selectively-optimized RubyInline version.  Instead  
of making the operations faster, Dominik changed the data structures  
slightly for speed to reduce work.
