Optical illusions play tricks on us, sometimes for the better and the worse. A rather bland situation can thus become a real headache for our minds. Suppose they constitute for some artists the very essence of their creative projects. In that case, they also inspire many Internet users who do not hesitate to share their diversions on social networks for their greatest happiness.

Don’t worry. Not your eyesight fails when you look at these photographs, but the insignificant little details hidden in the images. So don’t be surprised to see a Chewbacca-like beard made from a dog’s muzzle, a weird and terrifying Grinch-like tree, a hidden sandwich on a kitchen counter, or even two dogs as one.

We let you discover below a compilation of 30 optical illusions as funny as they are fun. And in a similar spirit, we invite you to (re) find 25 photos that reveal coincidences worthy of a bug in the Matrix.

Don’t forget to share it with your friends!
