I worked in a highrise office that had TVs ringing the floor that you could remote into to display dashboards and whatnot. One day I decided to play, on mute, endless episodes of How It's Made.

For reference, I work in a hardware engineering group. Some mesmerizing process would show up on screen, one person would stop and stare, and 5 minutes later we have a half dozen engineers who've stopped what they were doing to watch How It's Made.

Eventually we settled on Bob Ross as a happy medium in terms of "Pleasant Ambiance" and "Not Too Distracting."
