Here's a cool hack by Erik Terpstra for word wrapping normal text:

irb(main):001:0> str = 'This is a test of the emergency broadcasting  
services'
=> "This is a test of the emergency broadcasting services"
irb(main):002:0> str.scan(/(.{1,30})(?:\s+|$)/).flatten.join("\n")
=> "This is a test of the\nemergency broadcasting\nservices"

Hope that gives you some ideas.
