I can't tell you how much we hate sorting through Ruby on Rails logs looking for logger messages. This results in cruft like:

logger.info("========")
logger.info( "What am I made of? #{@someobject}")
logger.info("========")

Yuck. You know you do it too. So here is our solution:

Create config/initializers/logger.rb and drop this beauty in there. It will create two extra methods on Logger. Logger.dbug and Logger.colorize which will output a nice colored background on your message when invoked.

I made a Ruby gist for you.
