Static image of the previous animation in better quality.. stereo pair, crosseye-view stereo image

How to do it

- Sit square in front of your monitor, with the image directly in front of you, at about arm’s length

- Sitting further back makes it easier – you don’t need to cross your eyes as much – but makes the image look smaller

:bulletblack: Make sure you keep your head level horizontally, tilting your head will prevent you from merging the images

- While keeping the stereo pair of images in the centre of your vision, slowly cross your eyes

- The stereo pair will go out of focus and you will seem to see four images

- If you find it hard to cross your eyes, it can help to hold a pen in front of you and look at the tip with the stereo pair in the background

- Gradually cross your eyes more and more – if using a pen to assist, start it close to the monitor and move it towards your nose

- Continue crossing your eyes more, untill the centre two of the four images overlap and you see three blurry images, as in the animation above

- Try and hold the centre image together – it is possible to “lock” it in place and see it as one image

- The “locked” centre image should appear in 3D!
