How it works

In one sense, getting this to work could hardly be simpler. Just prop (or stick) the right-hand page of the centrefold against a wall so it is at 90 degrees to the left-hand page, which should be on a flat, horizontal surface. Then step away and adjust your standing position until the distorted image appears perfectly in 3D (see above).

Yet, in another sense, how this works is actually pretty complicated. Like any visual illusion, anamorphic illusions such as this one trick your brain by taking advantage of the way that we stitch together reality from our perceptions. Your brain can鈥檛 possibly process all of the visual information it receives, so it takes shortcuts. It constructs an image of what you are looking at based on previous experiences. Most of the time, the expectations match the real, physical world 鈥� but not always. When they don鈥檛, your brain unconsciously distorts your perception to meet those expectations, making things appear as something they are not.

Anamorphic illusions, from the Greek word for 鈥渢ransformation鈥�, have been popular since at least the Renaissance, when artists like Leonardo da Vinci were experimenting with perspective. Perhaps the most famous example is a 16th-century painting called The Ambassadors by Hans Holbein the Younger, in which a distorted shape at the bottom of the picture is revealed to be a skull when viewed from an acute angle.

How to make your own鈥� and share it!

In the anamorphic illusion featured in pur print edition and pictured above, the 快猫短视频 logo floats within a Penrose triangle, which is impossible in the sense that it can鈥檛 exist as a solid object. But you can create an amazing illusion based on anything you like 鈥� provided you can draw it 鈥� thanks to artist Lex Wilson. First, download and print these two grids. Then simply follow the instructions below.

We have also provided two more pairs of grids, together with instructions, in case you fancy experimenting with something a bit more complicated. To create a channel anamorphosis, which displays two different images when viewed from different sides, find instructions here 鈥� and download grids here and here. To create a concertina anamorphosis, which displays a 2D image across as a 3D surface, find instructions here 鈥� and download grids here and here.
