Wow, thanks for finding that PDF! I would not have had the first clue where to start. In the Fading section on page 5 there's actually a reference to "An Active Feedback System for Stabilizing Visual Images" (1975, DOI 10.1109/TBME.1972.324155), and going and reading *that* is actually making me question my memory of what I originally took note of - I remember a bit about mirrors, I think there might have been a mention of a person's head being secured, and the part with the handles was my own conjecture (I (again) think that the setup described that the mirrors were moved, but I'm not 100% sure). I'm wondering if this was the study that was being referenced?? Thanks! The linked paper and the reference paper are both extremely interesting *adds to collection* And it makes total sense that local anesthetic would be used to achieve paralysis, that's one brute force method lol Troxler's fading is infuriatingly annoying (mumbled in biology's general direction), like the "L R" blind-spot test; while I think need to go stare at the McCollough effect for a bit longer, the test pattern was ever so faintly blue O.o
