@Inginsub @RustyCrab Yeah I get weird visual effects like that all the time. This doesn't sound like exactly the same thing, like it's happening in a higher level system than that, but if I spend a lot of time pulling a specific kind of weed from my yard, I'll see its leaves whenever I close my eyes, like my brain is an AI model that just got trained on images of poison ivy or wisteria etc. Also when I used to play sprite video games as a kid, I'd close my eyes and see just random new characters with characteristics of what I was looking at. Only happened with sprite-based, pixel type graphics not like pre-rendered stuff for some reason. Also if I've been looking at curved stuff a lot, lines I know for a fact are straight start to look bent.
