"So, how are we doing today?" The blonde skunkgirl politely knocks on the door threshold before letting herself in. The eight inch metaluminum door slams resolutely shut behind her. She plucks your chart from the foot of the operating table, flips through it, and tucks it a lab coat pocket.
"Ah, for the pilot program! Of course." Her tail swishes. The pink tron lines flanking her stripe do this cool ghosting effect. So you can distract yourself with that while she checks your restraints. She hums to herself and starts flicking some nice, clicky mechanical switches outside your field of view. The machinery lining the walls clicks and pops and hums ominously. She hums along with it. She scampers around the edges of the room, occasionally dragging her tail across your face. It's soft and warm and like finding the sweet spot on the bed, except just kinda dropped on you while its owner makes sure the antiquantized rehelicasation engine is putting out about 32 mφ/s.
"Sorry about that! I wanted to make sure everything was warming up while I explained the procedure." That would explain the ominous whirring. "So! In a traditional Cooley–Tukey fast Fourier transform, we can recursively descend onto a signal, dividing, conquering, and reassembling smaller chunks to translate it into the frequency domain." She pulls down a chart with a bunch of sine waves on it. "In our new process, the fast furrier transform-" She pulls down another one with a bunch of anthropomorphic skunks in horny poses on it. "-we can do the same with a human, eventually projecting them into a cuter, fuzzier space. You can learn more about fast Fourier transforms at your local library. You know, after I turn you into a pony." She laughs at her own joke, then it's more of a general maniacal laugh as she throws the giant Frankenstein-ass switch on the wall. She fastens something cold and metal over your head. Electricity surges. Motors whir. Generators buzz and crack. Flywheels spin up, then stop cold. She says something about twiddle factors and the chirp-z algorithm.
Your mind breaks clean in half.
Then the halves break in half.
Then the quarters break in half.
Then the eighths break in half.
Then the sixteenths break in half.
And so on until the 8192nds break in half.
And each break is accompanied by a searing bliss right down the middle. Growing more numerous and powerful every time. A shock that makes it hard to reckon with the thin layer of fur growing on your body. Or the snout. Or the majestic mane. Or any of the other 16384 parts of you currently being twisted into something newer, cuter, and with a taste for skunkgirl cock.
As fun as it is having your mind diced into easily-washed chunks, the machine surges once more. Patches of fur merge into a big, soft coat. Fingers blur together into adorable, useless hooves. And you are making quite the adorable pony, what with your golden coat, strawberry mane, and butt tattoo that indicates you're suited for lab work. Disjointed memories and fragments of personality rejoin into a new whole. A new, helpful whole! Based on the person you used to be, yes, but projected into a new domain. Your hooves easily slip out of the cuffs and onto the floor.
"So, how do you feel?" The skunk asks, swishing her tail eagerly with pen poised over page.
"Like a brainwashed lesbian horse."
The part of your brain that used to be called head_slice tells you to say "I love it, Miss Grace!", and you do. And then head_slices  and  really like it when she scratches you behind those perky ears. You trot alongside her, listening to all 16384 parts of you that just love to help pretty girls do experiments.
You fucking love science.
