Nice try, Peter, but it ain't even close :^)

The red/green bar the original poster was referring is an XP
unit testing program know as SUnit or Junit -- there are variations 
of it in Smalltalk (original SUnit), Java (JUnit) and even
Python(PyUnit) and in many other languages. 

This is the first time I've seen it referred to as a green/red bar 
but I'd guess that its called that way because the GUI version 
(there's a commandline version as well) displays a progress bar 
that ends up green or red depending  whether all your
unit tests pass (green) or if 1 or more tests fail 
(the bar turns red).

Its an XP/Refactoring work-style to leave the unit testing 
program running and run your unit tests frequently as you make 
small changes to your program  -- thus reducing the risk that any 
change you make will screw up any other part of the system -- and
making you more confident to make really big changes that will
keep your code real clean, tight and totally cruft-free. 

Hope that clears that up (and hopefully no more wild references to 
canadian moose and beer will appear around here ;^))...

HTH.
