For a time I wrote code for BMS/BAS systems for many prominent commercial buildings in the NYC area, control rooms in basements and on rooftops and all the secret in-between rooms, in-between. (A fascinating job not without its exposure to asbestos, among other hazards.)

And, as someone born and raised in the south, I was thoroughly enamored with this ubiquitous font that implied the seriousness and purpose of each control implement, to include the priority of the functionality said implement represented, on countless panels I engaged with.

This deep dive was pleasing to my soul and I'm immensely thankful to the author for taking the time (and the photos) to indulge in traversing this wormhole for us.
