This is a nutty experiment, which, I believe, turned out quite well.
I set out this morning to dig into some of darktable’s mysterious modules,
simply to learn more about them.
The image was shot using a 28mm semi-antique, manual Vivitar lens,
developed in darktable and framed in g’mic.
Would you care to guess what it is that I shot?
[Clue: No, it is not Laura Palmer from the opening scenes of Twin Peaks.]
Have fun!

Looks like a frozen piece of plastic!
What have you learned about these mysterious modules?
It’s a foetus from The Alien films at 2 days old I think.
It is …

… interesting.
I recognized it immediately as the shed exoskeleton of this guy:
I always thought Covfefe would look like this.
My son says “shed snake skin”.
You owe me a perfectly good laptop display, to replace the one where hypersonic coffee molecules have settled deep in the plastic.
Frozen (used) condom? Frozen snot? Peeling human skin? Moulting/Ecdysis of some insect (even I don’t win, I’ll have learned new words).
If I had to guess, it might be a plastic piece torn off a food package. Maybe defrosting, maybe not. It is hard to tell due to the processing. For I know, it could be @Claes’ dead skin. I also thought drugs, though that would be unlikely; just an unfiltered thought. Don’t take drugs kids.
there is that fabric-imprint in the middle, so I go for some plastic that was glued on fabric and isn’t anymore. Packaging-something-tape?
It looks like an ice shaving made by stopping during ice skating.
Yes, he will… 
Quite a lot, actually.
I have never before dug down into every dt module, one by one, in order to find its limits.
When ? 
We have a winner!
Congratulations, @afre!
Yesterday lunch, I had to open a piece of cheese, protected by an armoured piece of plastic, using my trusty Opinel #10 knife. Some bits of cheese fell off, and the welded plastic seam crumbled nicely onto the kitchen sink. Here is (more or less) the un-treated shot:
I am still impressed by how darktable could handle it
Have fun!

I thought it was from a cheese, but the processing made it look much smaller in scale like a scanned-electron micrograph.
These are really good knifes 
Edit: at least the version without the t which can be made extremely sharp
