This 57-second clip is a stream of short and long Morse code beeps that spell out the warning, 'If you're reading this turn around.' The steady tapping feels secretive and playful, like a hidden note passed in class, and it builds a quiet sense of suspense as listeners wait to work out what the code is saying.
