@brucelawson Bruce what do I do if I donβt enjoy the circles, theyβre distressing me @hejsna stare at them until you enjoy them. You MUST enjoy the circles.  @sarajw it's mad, isn't it? I had to draw circles over it in an editor to verify it is just 2 circles.  @brucelawson if you cover the top half then the bottom half itβs easy to see just the two circles. @sarajw  @brucelawson then you might want to change the one on this picture to not just be a funny funny joke but a bit more descriptive @codingcatgirl in what way is it not descriptive? It's how it appears to me. @brucelawson @codingcatgirl agreed, I think the alt text describes the visual experience extremely well  There is something deeply fundamental about the way the visual system parses images with dark and light components. This example is particularly compelling. I feel certain extant models of visual perception are missing some fundamental idea involving opposite polarity edges and how they are combined into representations. Hereβs another example from my own research some years back. The rings seem against high contrast backgrounds seem lustrous and appear to shimmer.  @brucelawson @TonyVladusich Is the one on the right animated or does my brain make the background suddenly and dramatically change colour? Aaargh.  @TonyVladusich @sbszine @brucelawson does it mean anything that I do not see the shimmering effect you're describing? @brucelawson I take that and raise you a map showing the GB rail passenger flow for 2022/23.   @brucelawson This broke my brain. I then shared it with my wife, where she asked why I would do this to her after a week of 5 Mondays in a row. Thank you for the laugh.  @tunetheweb Revenge for all the perf acronyms you force me to parse, Bazza @brucelawson Itβs LCP not LSD. Itβs TTFB not TRIP. Itβs TCP not PCP. Ok Iβll stop nowβ¦  @brucelawson huh I broke the illusion by squinting (our biological low pass filter :p) and now I can only see two concentric circles with texture... Is it just me?      @brucelawson if I hold the pucture far away enough, so it turns blurry (about arms length, without glasses) I can see the two circles without issues :p  @brucelawson Water boarding for the eyes. Never get good information like that. Just tell me what you want to know and give me a Coke   @brucelawson So what you're saying is that if I do visit Birmingham, to turn in early? Because those hoops are way too lively without even having any gyrating hips in them.      @brucelawson@social.vivaldi.net  The illusion is by Kitaoka Akiyoshi, a Professor of Psychology at Ritsumeikan University, Kyoto, Japan. He understands visual neurology and has constructed many illusions. His Wikipedia page has links to his illusions pages. @weaselx86 Thanks! I nabbed it from something a mate posted on Zuckbook @brucelawson I looked hard enough until I figured it out, then read the alt text and thought Cixin Liu should have written The Two Circle Problem because The 3 Body Problem is simpler math. @brucelawson Wow, this is the closest thing to the visual aura symptoms I get at the start of a migraine attack. Looking at this actually triggers a headache...  @brucelawson NO! Don't do that to my poor eyes... CW it... (sorry everyone else with the same issues... @atrus if you stare at them non-stop for 3 to 4 hours, you will. Trust me.   @brucelawson     |
