def type(string, speed=5)
  old_sync = $stdout.sync
  $stdout.sync = true
  string.each_char do |c|
    print c
    sleep 1.0/speed
  end
  $stdout.sync = old_sync
end

type "foo\nbar\bz"

This will type 5 letters per second (the default value for speed), first 
typing foo, then a newline, then bar and then deleting the r in bar and 
replacing it with a z.
So put this method definition at the beginning of your script and then use 
type instead of puts. If you're using ruby 1.8.6, you'll also have to 
require 'jcode'  at the top of the file.

HTH,
Sebastian
