Let us revisit the Seemingly Bent category. We hadn’t had unique optical illusion that belongs to this section, in quite a while. To remind you once again, Seemingly Bent category consists of illusions that give you impression you are seeing slanted lines and shapes, while in fact they are perfectly straight (or mutually parallel).

This is an oldie, but we rarely see this kind of optical illusions in its full effect. Ok, this is what I want you to do: count how many different colors you can see in this spiral below. Unfortunately color-blind individuals will only see a grayish pattern, so this won’t work for them (those of [...]

Be sincere, what whas the first thing you thought for yourself, when seeing this image? I was sure it was just an oridnary spirall, but when observing it more precise, I figured out it’s actually a bunch of concentric circles… Hillarious! Did you get the same effect?

Is there spiral on this Image? No, it’s actually just independent circles!
