That’s genius. I was always more of a screenshot-your-desktop-then-set-it-as-wallpaper-and-hide-taskbar-and-icons kinda guy but that one is so damn subtle it probably just leads to people thinking everything works normally except that it feels ever so slightly off, but they can’t put their finger on it. I like it a lot.
Sounds like k3s would be right up your alley, it’s API compatible with k8s but has a lot less overhead than k8s, designed for use on low power devices like the Pi.
