They'll complain that a magick eye is supposed to look Interesting to try removing bits of your picture to see the effect.ДЄ lot can be learnt from the simple autostereograms Image the other doesn't, and the brain will realise it's being fooled. Idea of what it's seeing? It thinks more widely-spaced things mustД«e closer, so the buffalo must be closer than the parrots. Looking at the same parrot, whereas in reality they are We trick the brain into thinking both eyes are So your brain interprets closely-spaced fencesДЄs far-away fences. Is by how many panels you can see compared to Sized, so you can tell how far away a row of fences Imagine looking at a set of rows of garden fences Of course, we chose this because your eyes are displaced

Of the crystal, by choosing to move in the x-direction They have spontaneously broken the symmetry The electron field - at high temperature there's a buffalo with every parrot,Д«ut as the system is cooled suddenly the buffalo move apart in the x-direction, In the analogy the crystal lattice would have a basis Spacing makes a nice analogy to charge ordering and The addition of a second set of images with a wider In this image I've used buffalo and slugs withДifferent spacings so that they jump either in Now we'd like to add a second layer of images over theД«ackground, but crucially these will have a different Your 2D crystal lattice, and the image you just chose In crystallographic language the grid was Unfortunately the file tends to be rather large because it contains many I got a picture of some beautifully-coloured parrots and greyscaled them: So the eyes have an easier time believing the lie. The picture must be the same in each cell on a row,Д«ackground I recommend making all cells identical and not too exciting, Next you'll want to put an interesting picture in each cell (although this is not strictly necessary). Press F6 to select the straight line tool, andДЇill in the grid. Rows available to jump different distances. Picture will be more exciting if you have different They y-direction doesn't matter so much, but the In the x-direction (matching the spacing of the eyes). I find a spacing of about 130 pixels is best The trick will be toД¬ross the eyes so that both think they're lookingДЄt the same cell, but are in fact looking at different cells.Дrawing a grid on Inkscape is straightforward. The most basic autostereogramД¬an be made by drawing a 2D grid. Seeing slightly different images (although there's a lot of We know that 3D vision is due to the two eyes Step 1: crystallography and charge ordering

I'll give a step-by-step guide to how to do this, I learnt to see the images by making them myself. The usual advice is to put your face close to the screen so your eyesД¬an't focus on anything, cross your eyes a bit (made easier by the first step),
