Ok it took me a while to “see” it at first, but now that I do I really am curious as to how it works. I also find it fascinating that zooming in and out makes it easier or more difficult to see.
I tried zooming way, way in on the image, to look for little pixels here and there, but the more I zoom in, the less I understand.
When I zoom way out (so that the image is small), I can see very clearly without having to do the trick to seeing it.
Here’s a hint on how to see it if you are not sure how:
If you can’t see it easily, blur your vision a bit by unfocusing on the screen
So, how does this work?
