Window-switcher: A co-worker of mine asked me to help him alternate windows on their display. Stats for x seconds, mission statement for x seconds. Here's the 5 minute result.

window_switcher.rb

#'compiled' with Ocra
require 'win32ole'

@wsh = WIN32OLE.new('Wscript.Shell')
@title1, @title1_seconds, @title2, @title2_seconds = ARGV
if !@title2_seconds
    puts "usage: window1_title seconds window2_title seconds"
    puts "ex: Skype 10 Untitled 5"
    puts "note: you only need to match the first letters in the window title."
    puts "'Untitled' will find the 'Untitled - Notepad' window"
  exit
end

puts "\n\nControl+C to exit\n\n"
def alternate_window
  @wsh.AppActivate @title1
  sleep @title1_seconds.to_i
  @wsh.AppActivate @title2
  sleep @title2_seconds.to_i
end
begin
loop {alternate_window}

rescue Interrupt
  puts "\n\nThanks for playin'!\n\n"
end
