Okay, this might not look like a lot, but, if you take a closer look at it, you’re going to see that it’s an impossible object. The Devil’s fork or the Blivet, is what you should check out in this image. So, take a close look at it, and then try to wrap your head around it. Quite hard, isn’t it? Well, let’s take a closer look at it, and try to decipher it.
What to see
If you look the Devil’s fork, you quickly see that the image that’s depicted is impossible. Actually, the Devil’s fork or that Bivet – no matter how you want to call it, it’s three things in one: an optical illusion, an undecipherable figure, and impossible object – in real life, not on paper, naturally. Why this? Because the Devil’s fork seems to have three cylinders, but on the other end, there’s not the same thing happening. The funny thing is that the more you look at, the more it looks like the image is simply impossible.
How it works?
Well, there’s not that much to say actually. Because it’s a drawing on paper, everything is impossible. However, it seems impossible because the way that our brains reconstruct an internal 3D world model from a flat retinal image. It’s more complicated than it sounds, and, well, you can’t really say this about everything today, can you?
