Hi,
I've seen this screencast<http://www.engineyard.com/blog/community/scotland-on-rails/the-ruby-object-model/>in
where the presenter is editing ruby code in an editor, and everty time
he
save's the file, the code exectute in an other window with really cool
colors and really fast! excelent for debugging or when you are learning
something new.
anyone knows what is the program he is using?

regards!
