Re: Office background
The first time I had to visit the orifice during lockdown I did just that! Took a photo from the spot on my desk where the lappy camera would be located, and uploaded it to use as a backdrop.
One colleague had to be in the office (with appropriate measures, etc.) during a network change that would take out the VPN endpoints for a couple of hours. So no possibility of doing that remotely.
So now he has a background showing the view from his desk. With the Train Destination Display[0] sitting on a cabinet behind him prominently visible, the clock showing twenty minutes to four, the display empty and a dark window in the corner showing that it's 3:40AM, hence the lack of info being shown[1].

[1] Of course it works, and dutifully shows the departure time and destination for the next train at platform 13b. The whirring of the flap display is one of the few things I miss from working at the office.
