A simple ruby script for displaying fancy terminal screen

matrix

#!/usr/local/bin/ruby
# matrix test with ruby
# Used Two Gems 'curses' for terminal cursor moving and 'rainbow' for coloring
# first run "gem install curses rainbow"
# then run this file
# Note: you can tweak parameters when initializing the object
# Enjoy :)
