Failed Attempts To Theme Windows

So someone faved one of my artworks on DeviantArt. And naturally I had
a look through their faves, to see what else I might find interesting.
And eventually I worked my way to this
<https://www.deviantart.com/pitkon/art/Blackbox-309930439>, which is a
theme for the Blackbox window manager.

But more than that, for a while there was a project to run Blackbox on
Windows. The links in the blurb for that artwork point to a screenshot
repository, last updated over a decade ago, and to a project home site
and forum site, both now gone.

Trying to install alternative GUIs on Windows was never going to be an
easy task ...
