Great visual illusion, accompanied by a lovely variation on Shepard Tones if you have the sound on Posted on Reddit by bigjobbyx, who is a bit of an artist genius

Food for thought: AI probably can’t reliably generate visual illusions such as this. (I am sure it can generate plenty of things that *could* be illusions but how would it test it without a full working model of a human perceptual system?)

The footsteps illusion-like pausing and sticking illusion The rectangles in the upper half appear to move to the right and stop periodically; however, they are moving to the right at a constant speed in the same way as the rectangles in the lower half.
Some people say we don’t build beautiful things anymore and, like, lol. Motherfuckers, we built this:
This story just keeps going: Giant octopuses of the Cretaceous were probably the top ocean predators of their day. They were up to 19 meters (60 feet) long, snacked on plesiosaurs and mosasaurs, and were probably quite intelligent. Sorry we missed you! 🧪 www.science.org/doi/10.1126/...
Once upon a time I just admired nudis and sea slugs. But it was not enough. Now apparently I'm creating an R package to celebrate their colour palettes? 😅 First up, my Sydney fave, Hypselodoris bennetti. #rstats #nudibranch #dataviz 🦑🐙🧪 #marinelife #invertebrates

Pascal Mamassian@mamassian.bsky.social · 11mo agoA nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue. The effect presumably comes from the absence of S-cones in the fovea. From Hinnerk Schulz-Hildebrandt: arxiv.org/pdf/2509.115...

Cow Tools! We have lived alongside cows for nearly 10,000 years. We breed them and exploit them It is now, only now, that we have discovered THEY CAN USE TOOLS Here I describe our study (paper) www.sciencedirect.com/science/arti... in @currentbiology.bsky.social with @auersperga.bsky.social

Penny Allman-Payne@pennyallmanpayne.com · 7mo agoRich private schools are gouging parents with huge fee increases while also pocketing millions a year in govt money – yet 98% of public schools don’t get their minimum funding. Should Labor be pouring billions a year into the private system while public schools are underfunded?
This head is spinning continuously, but we see it rotating back and forth... ...presumably because of our strong prior expectation that faces are convex. This is a very nice example of the Hollow-Face illusion promoted by Richard Gregory: www.richardgregory.org/experiments/
Beau Miles. One of my favourite YouTubers, a genuine human, being his awesome self. And so watchable too, he can really tell a story. youtu.be/T5YF95r_Bew?... This video revenue will plant trees. I love this, he’s documented the whole process, transparently, no BS. This is how you do it.
