Clean operating system?

Funny j.e.f.f., I used very much the same approach. :-)

@chaseb1357 Well as long as they don’t connect a keyboard and mouse the the Raspberry Pi, and if they don’t have the SSH password, there’s not much they can do. Maybe see if you can mount the raspberry pi inside a case that will block the USB ports.

Someone suggested this about a year ago, but I don’t think anyone has tried.

But BENJA in theory might work: https://benja.io/

@j-e-f-f: where I can download this wallpaper in better quality?

[j.e.f.f]

@Fifin404 no idea. I used the image as-is included in the MagicMirror project and just centred it as the background on Raspbian.
Maybe contact @MichMich, the author of MagicMirror to see if he can provide you with a better quality version of the image.
