I don't see any difference between the two pictures when I look at them separately.

If you cross your eyes and line up the photos. They line up.

The "illusion" is because the right and left side angles in the photo are are different, so when you put the same photo next to each other, the differing angles right next to each other make the two copies "seem" different.  Once you realize that, it is actually incredibly easy to see they are both the same.

binocular vision, how does it work?

There must be something wrong with my vision or something. I can see that they are two separate images.
They don't converge in any way to me.

The illusion is that the lighter line down the middle of the road seems to converge. The line on the right looks 45 degrees while the one on the left looks more vertical. They are in fact the same angle.
 
OOF

I'm so glad to see this is a thing. In an office building, there were 4 TVs showing the same football game in the lobby. The lines on the right side looked like they angled left. The ones on the left looked vertical. I couldn't figure it out.

It's simply the brain "cheating" to compensate for a lack of visual processing power.

A & B are the same?

Yeah.

Stupid lying brain....

When I do that with the leaning tower one, it looks fairly 3D to me. Neat illusion for being the exact same photo. :)

Looking at any two identical photos side by side cross eyed (parallax vision) will produce a 3D image. Try it with identical topographical maps.

Yyyyyyup. 100%. You can eyedropper the pixels in Photoshop to get the color codes if you are still skeptical.

Being left eye dominant, the effect is barely noticeable. I don't read it as two different pictures. Just the same photo with the right side photo slightly skewed... Do any right eye dominant people see the opposite, I wonder?

HOLY FLYING BUGGERNUTS.

That is quite freaky, I have to admit. WTF. The human brain is effing wonderous! :-)

I've been dabbling in stereography for 10 years and did NOT know that.

I'd LOVE to be able to actually have a reddit experience where my brain didn't try to leave me via my aching, tortured, eyesockets.

I reiterate: I simply can't use reddit. Turning all text to Comic Sans on that site wouldn't make it much worse IMO
