If you following my last NFTs you know I create 3 Stereograms with a big Bitcoin Logo on center of image.
"Stereogram, in my 3 NFT cases also known as Autostereogram, the "hidden" image appears from the background plane, when the stereogram is viewed with proper eye divergence." - source: https://en.wikipedia.org/wiki/Autostereogram
Get the stereogram image really close to your eyes, you can even touch it with your nose.
Now your eyes can't focus the image, slowly move the image away from you, try to keep the eyes off focus during the slowing move. At some point of this move you will see the hidden image.
Other technique is look to your finger, cross the eyes till see 2 fingers, not exaggerated. Move the eyes to the image without losing the focus you get on 2 fingers.
