Checkerboard
Not such a silly idea really.
You had a laugh, but it got your attention - and - you still remember it to this day.
When you are receiving dozens of resumes its the ones that are 'a little different' that stand out from the crowd and will get looked at first.
Having said that, if the contents don't match your expectations the job will most likely go to someone more suitable, but at least they got a look in!
