L'association de la Science et des Beaux-arts peut donner ce type de fascinante illusion d'optique :shibahearteyes:

Musée des Beaux-Arts de Houston, Texas.

Explication :
Il y a une façade de bâtiment au sol, avec un miroir géant incliné au-dessus à un angle de 45 degrés, de sorte que, vu dans le miroir, les visiteurs semblent se balancer sur le côté du bâtiment.

Une bien fascinante illusion d'optique :shibahearteyes:

These vans are the same size. The middle van was copy-pasted without changing scale.

Measure them 😅

Y’all hear of cloud iridescence (also called irisation)? It’s an optical illusion when clouds are impacted by the sun or moon. Like soap bubbles.

It’s a real thing and it’s gorgeous. I’ve seen countless photos/videos of the phenomenon, but never in real life. Maybe one day?

I really like the effect of the two variations of Professor Kitaoka's rotating triangular rings illusion that I stumbled across. When the gradients are aligned differently, they either create an expanding effect (image 2) or a contracting effect (image 3). I haven't seen these variants online, though they were likely already covered by the prolific Kitaoka.

I added variants or reveals to several more of the illusions. Not all of them would have a place for that feature, or it is covered by the regular interactions well enough, but many do benefit from it, like these four.

#opticalillusion

I added four illusions (two are variations) to my #opticalillusion collection. I improved the hexagon variant to have better proportions than the hastily made version. I updated the interface for easier navigation and easier access to the features. The category button will skip to the next of the three categories. The bottom right button will now activate the variant/reveal toggle, rather than requiring a key press or three finger touch.

Is the pattern moving or perfectly still?

I added a cool one to the #opticalillusion collection this week. I figured out a way to replicate @ronikaufman's recent Truchet spiral images (https://openprocessing.org/sketch/1978420) using relatively simple nested loops of circles. This allows it to be scaled up to high resolution without issues. I got his permission to add it, and also incorporated many variations, including several new ones, that can be uncovered through interaction.

Today I added Adelson's Snake Illusion to my #opticalillusion collection. I used quadratic vertices for the wavy shape on an image buffer. Also, thanks to a request from @AaronReuland, I added an information button to toggle a display of the key details about each illusion. I restructured the code to contain all of the information and properties in the main illusion array by setting up an object for each illusion.

That lines are perfectly parallel.

To prove this to yourself, just squint at the image or look at it from the side.

I only added one more to the #opticalillusion collection this week, because I spent a good while refactoring code and debugging. @davepagurek set @AaronReuland and me straight on the proper use of image buffers to avoid crashes. Create once, then resize and clear as necessary, rather than creating anew each time. A few of the illusions can now run at the full framerate with no issues. Smooth. That will definitely help with other projects.
