look at this picture and select the person who is smiling and the person who is angry go back 2 meters from your screen and look again, what do you see?
there are 2 faces, right? one on left and one on right look deeply on each face and determine the person who is smiling and the person who looks angry... now stand up and go back 2 meters from your screen and look again.. what do you see?
I understand what's supposed to happen. And I know what two meters is. If I cross my eyes, I can see subtle changes.... It just doesn't change on my screen. Sorry.
it works for me , and you dont need to move away from your screen just really squint your eyes and you can see the image on the left is smiling
I'd have to knock out a wall in order to attain 6.0 meters. and unfortuntly it's a *load bearing wall! I saw a slight smile from the left but I was only 2.884 meters away at the time.
A nice find... But the trick is a bit predictable.. I already had a feeling that the other was the one angry from the beginning of your post.
