Every so often, I like to write a Ruby script that says good morning to my team in a fun way. Here is the one I made this morning which mimics the famous bouncing DVD logo.
require "io/console"; greeting=[71,111,111,100,32,77,111,114,110,105,110,103, 44,32,84,101,97,109,33].map(&:chr).join; colors=["\e[31m","\e[33m","\e[32m","\e[36m","\e[34m","\e[35m"]; rows,columns=IO.console.winsize rescue [24,80]; g_width=greeting.size; g_height=1; x=rand(columns-g_width); y=rand(rows-g_height); dx=1; dy=1; frame=0; loop do print "\e[H\e[2J"; puts "\n"*y; color=colors[frame % colors.size]; print(" "*x+color+greeting+"\e[0m"); sleep 0.05; if (x+dx<0)||(x+g_width+dx>columns) then dx=-dx; frame+=1; end; if (y+dy<0)||(y+g_height+dy>rows) then dy=-dy; frame+=1; end; x+=dx; y+=dy; sleep 0.25; end
