[Plasma], with some '90s UNIX CDE flair

Plasma 5 on Debian Trixie (though technically a frankendebian with some packages from Bookworm and Sid, shh don't tell https://wiki.debian.org/DontBreakDebian)
Commonality theme
Oxygen icons for the skeuomorphism
A spattering of widgets, all included with Plasma
Berkeley Mono typeface, system-wide

I have two monitors, this is a screenshot from my more-or-less secondary monitor - hence having all my dashboard-type things on it.

The photo widget is rotating through a folder of some photos I've taken that I'm fond of.
