Very interesting concept, and it's written well.
LilyFlower is cute and amazing <3
Is a sudden, 'in a blink' change, or is it noticeable how parts elongate and change?
I didn't see that explained, I may've missed it.
The last note made me think of 750, and I was left underwhelmed. For me, the general concept is pretty interesting, but the way it's executed and what it's trying to do is not.
To me, this is in "random thing what does a random thing" territory. The body horror was decently described, but the delivery mechanism to get there didn't seem to bear any sort of relation whatsoever to anything else in the story.
I also did not care at all for the pontificating note at the end. In-universe, the researcher would have no reason to think any of that stuff, and would not include it in a scientific document. Out-of-universe, I never like having things directly explained at me, the reader, by a Dr. Author character.
The body horror's good, the clothesline that terminates midair is good, a bit of magic like we haven't been seeing around here lately, but the two effects don't really seem to have any link. I feel like there's some underlying thing going on here that I can't figure out.
I'll agree with other people here - the body horror is very good, and described quite exactly and horrifically, and I like the bizarreness of the clothesline, but it all feels a bit sparse… a tiny hint of what's going on and why would be nice.
For those who don't get it, the other end of the clothesline is somehow attached to a point in N-dimensional space. When you grab hold of it, you "lean" just slightly outside of 3-dimensional reality, permanently. The distortions are the the result of the person being percieved, not just visually but also physically, at the wrong N-dimentional angle. The variations would be the result of minute differences in how and at what angle the clothesline was grabbed.
To an instance of 2252-1, anything still aligned to "normal" space-time looks similarly distorted, while they themselves remain normal, hence they only freak out when they take off the blindfold and find themselves in an nightmarish alien landscape, surrounded by horrifying entities.
You can create effects similar to some of the descriptions in a 3d graphics program by slightly de-aligning a human model's skeleton and/or textures from its mesh, and/or applying "warp" modifiers at poorly chosen strengths and angles; the results can indeed be quite horrific. Test #1, for instance, would be the result of applying a "contract" modifier with a narrow, oblong field of effect intersecting from the right cheek to the left ankle. The more complex body distortions are somewhat like the 3d equivalent of a kalidoscope, and would involve multiple hyperdimentional rotations.
Extremely creative and well written SCP, deserves a much higher rating. +1
Noticed a grammatical error; there is a missing period on the second line between different and Its. Otherwise, a well written SCP.
