As far back as the late 1970s a surprisingly similar scheme was used to record digital audio to analog video tape. It mostly looks like kind of stripey static, but there was a clear correlation between what happened musically and what happened visually, so in college (late 1980s) one of my friends came into one of these and we'd keep it on the TV while listening to whole albums. We had a simultaneous epiphany about the encoding scheme during a Jethro Tull flute solo, when the static suddenly became just a few large squares.
