If your terminal/putty/shell window stays colored after running this (as mine does, which is a little annoying :) and you're not familiar with shell escapes for colorizing foregrounds/backgrounds of terminal/putty/shell windows (as I wasn't), be sure to have on of these handy for resetting your colors to the way they were:
perl -e 'printf "\e[0%dm", 0'
:)
Update: D'oh! Yes of course. I was busy just replacing the line from the excellent explanation above:
printf "\e[$escape;%dm", int(rand 6) + 101 - 60 * ($is_windows || 0);
... with something that wouldn't leave my window a different color that I didn't even bother to shorten it beyond printf "\e[0%dm", 0. But seeing liverpole's comment below, I feel completely silly for not "golfing" it further.
