Of the many many things my Dad taught me, he taught me to appreciate things that are mysteries in life. He taught me that life isn't fair (right Dad?). But he also taught me that it does offer mysteries, paradoxes, ironies and conundrums. That's pretty cool.
Dad specifically requested that he didn't need anything for Father's Day, but what I do know is that he will appreciate this simple auditory illusion. It's called a Shepard tone.
Happy Father's Day, Dad.
