Here is a quick little script to illustrate loops and the Term-Ansicolor gem:

require "rubygems"
require "term/ansicolor"
c = Term::ANSIColor
print c.white,c.bold,c.on_blue
print "                                           "
puts
for w in 
[ "words","in","an","array" ]
	print "   "+w
end
print "                                           "
print c.reset
print "\n"
