To be honest, me and a friend had a beer or two yesterday night. Maybe that's why I got so excited about a little funny optical illusion I accidentally made while playing around with a piece of carton. The effect is the same as this cute little dragon shows, turning his head while you walk around him.
My version is a little bit simpler... :D Draw a square on a piece of paper with diagonal, horizontal and a vertical lines, cut it out and fold it along the lines, so that the lines are inside:

Now flip it over like this and try to imagine that you are looking at the top of a pyramid from above (like on the right image above).
Move your head slightly and you might see the top of the pyramid following you. It can take a while to trick your brain. If it doesn't work for you, close an eye, try it on a plane surface without distracting objects, focus exactly on the "top" for a while and really imagine you're looking from above, then move your head slowly.

Bonus Tip: Folded paper makes a great ruler.

Ooh I remember this one, I used to have one on my desk for years. Maybe I'll print one again, always useful to distract colleagues who come by with pesky questions :P
Yes, it's a quite common illusion to be honest. It was just very funny because I really accidentally tricked my eyes yesterday for a moment. I wasn't sure if it was only because of the beer but it works even without... :D
I first saw the dinosaur one on an episode from "brain games" on natgeo. We humans identify faces judging by the placement of eyes. It's cool to see you try the same without relying on eyes.
Kahnemann calls them perceptual illusions, which is basically proof that "I have to see it to believe it" is not necessarily a good approach to life.
He explains it here:
Wow, really cool illusion 😊 like it a lot.
