I still fondly remember an occurrence from years ago.
I had a dwarf go moody and received a message that she had claimed a workshop.
I gave up looking for her after a while, but imagine my surprise when my 3D printer produced a plate! The image of an image of cheese was... mouthwatering to say the least.
Yeah, I had that happen once. Only I had a recursive image.
It was accurate down to molecular levels.
My 3D printer doesn't have that much resolution.
Spooky.
I'm another, here, who had that problem. I say 'problem', because in my case it was a training weapon. And it was during the period when a Training version of the then-new-fangled non-lethal weaponry options was the exact functional inversion of a Training version of an actual dangerous weapon. Cue some explaining needing doing to the authorities...
(And later on the distinct feeling that either I or the Dwarf Fortress Hive Mind was then done out of royalty payments. Remember the news reports of the New Tuvalu rebels being 'pacified' the fifth, perhaps sixth, time round? Yes,
that thing... And, yes, that probably
does explain how it became a significant part of the Fractal Cheese War Machine Meme thing, that summer.)
