One of ColdFusion's best features is it's CFDUMP tag with awesome
visual representation of data, especially for objects, arrays, etc.
For PHP there is a class called dBug created by Kwaku Otchere
(http://dbug.ospinto.com).  It is basically a port of cfdump to PHP
with an identical visual style.

So I was wondering ... has anyone done this for Ruby on Rails?  Or is
there anything similar?
