If you look at these discs from a distance, you will see distorted images. However, if you lean forward and look through a glass sphere, the images suddenly make sense. #OpticalIllusion
all the lines in this picture are straight. But, presumably because of the hashed keep-out zone, the outline of the ESP32 looks tilted. Is there a name for this?
So I was experimenting with text stuff, and realized that if I full screen and have this zoomed to fit my screen, that looking from the + to the = and back will make the whole thing look grey!
For the #Genuary24 topic of "Impossible objects (undecided geometry)", I just had to add to my #OpticalIllusion collection. I made an interactive version of Reutersvärd's Triangle. It's the original (and my favorite) version of the later discovered and more widely known Penrose Triangle.
With the new faster blur filter in #p5js, It is now possible to integrate it into an interactive #opticalillusion, so that's just what I did over the last few days, with a few I had on my to-do list.
I didn't understand what was going on with the one with the diamonds until I analyzed the image, recreated it, and played around with it for a while. It's one of the cooler illusions I've come across.
L'artiste sud-africain Strijdom van der Merwe façonne les matériaux en un art géométrique qui vient compléter l'environnement. Son « escalier vers le paradis » est une illusion d'optique simple mais impressionnante. J'adore 🥰
You might recall my interactive #opticalillusion collection that I've worked on this year. I got stuck on one, then focused on other projects, but I finally made something new and different for it this week. I experimented with a new system I call Dazzle, Tilt, Zigzag, in which I have found several different illusions. They're not new effects, but the compositions are, and the system is fun to play around with. See the alt texts for more details.
Here's another interesting #opticalillusion I found in it by converting one config of the color variant to grayscale and then increasing the contrast and rotating it. The line grid network seems to be very distorted and wavy to me.
Dans cette illusion d'optique, il y a deux cercles parfaits que votre cerveau "refuse" très prochainement de voir ! 🥰
Dans la deuxième figure, exprès en plus petit pour être lisible, j'ai ajouté deux cercles en noir pour casser l'illusion et confirmer le point précédent.
