That's amazing! Within 40 seconds I overlapped the two hard mode images and saw 8 shimmering objects set within a clear picture. It took me a little longer (maybe a minute), but the two impossible mode pictures snapped together and I saw a single shimmering star within an otherwise crystal clear photograph!

You can make the impossible picture (the others too) easier by slightly moving your head back and forth while superimposing the images. The difference will move more than the rest of the image.

What's astounding about this is simply the staggering amount of visual processing your brain is capable of doing in parallel.

We know the direction a sound comes from due to milliseconds of difference of the soundwave arriving in one eardrum and then the other...

Totally indulging in this side discussion: I remember thinking in high school and college that fame was the end-all of life, telling people that my goal was to have my own Wikipedia page. I saw it as something like the combination of being a "cool kid" (but for, you know, the whole of society instead of just one's school) and a sort of immortality. Anyway, over the last couple of decades as an adult, besides realizin…

Length of remembrance aside, the idea of fame as immortality has always confused me on different grounds. It's not how fame works: we remember factoids, not people. It's a bit different if the fame is a work of art, but then the thing with immortality (sort of) is the art, not the person that made it. I might remember 7 things about Teddy Roosevelt, which are admittedly very cool and impressive things, but those thin…

You make good points. When I looked up the word "immortality" in Merriam Webster while writing my first comment, I found it interesting that one of the definitions was actually "lasting fame."

> we remember factoids... I might remember 7 things about Teddy Roosevelt... but those things do nothing to represent the complex individual he actually was.

I've thought this before when looking at Wikipedia pages. Especially for less famous people with thin pages, they'll cite just a handful of news articles or press releases in which the person appeared. If there were a page like that for me, or the people that I know best, the collection of factoids would be a laughably inaccurate reflection of who we really are. Someone told me that it's important to write an autobiography for this reason.

You may have a very slightly 'lazy eye' (I do) - it can be a lot less extreme (not at all noticeable to others) than the pointing-completely-different-directions that people imagine, and iirc is highly correlated with astigmatism. Optician used to tell me to work the muscle by following my finger to my nose, trying to maintain a single image. At a certain point it will snap into two - the 'lazy' eye has given up and…

Same, and I had no idea it was correlated with astigmatism! That does explain my prescription

I’m also unable to do this for whatever reason but using a stereoscope works.

Back when I studied media and communications, around when the first avatar movie created a hype for 3D movies. Me and a couple of friends decided to try and make a 3D movie for class. We made a custom camera rig out of metal brackets and edited the movies cross eyed since we had no actual way of editing in 3D, worked like a charm, altho, it was really hard to get the 3D right.

For anyone who wants to learn this, try this way using your finger as a helper. Put the images in front of your eyes. Bring your finger between your face and the image at almost middle of the distance. Now look at your finger. Move your finger back and forth and notice the background (where your picture is) While doing this, notice that at a particular distance, the images in background will perfectly overlap each ot…

Does this only work on desktop? I am trying this on mobile and the images never overlap. Wondering if maybe my viewport is too smal

Here are some tips; 1. When you cross your eyes, gradually let them return to uncrossed. Try to do it as slow as possible. Along the way, try to line up any structures that you see in the image that are repeated from left/right half. 2. Once you are able to hold a cross-eyed gaze long enough with lined up left/right half, slowly move your eyes between different features near the middle. Your eyes will naturally want…

> 1. When you cross your eyes, So, how exactly is that supposed to work? I can manage some de-focusing which makes me see 4 images rather than two. Is that part of it? Otherwise, I don't get it.

That's exactly it. You have to bring the "copy" of the left side to overlap with the "original" right side. Then move forward/backward until the overlapped 2 come into focus. The shimmering should stick out, was so shocking when it finally clicked for me.

A new way of doing git diff, leave both versions of the code side by side and cross your eyes.

It sounds like you mock, but: you can do this, or near enough, and you can do it already, and it works really well!

0. Pick suitable tool. Firefox works. Notepad++ works. GIMP works. Emacs, not so much, but if you use Emacs, you know that you can fix this

1. Load file A into a tab

2. Load file B into a tab

3. Close all other tabs

4. Hold down the tab switch shortcut key and note the result

For images this is actually pretty decent and I've used it a lot. Good for figuring out what the differences actually are when your image-based tests fail, and similarly after making a speculative change. Let your eyes do the difference operation for you. That's what they're there for.

For text: you'd be better served by some other kind of tool. But text is just an image with letters in it, so the same principle applies. It does work!

(I've previously read a blog post, link to which I of course now can't find, about how old-style Photoshop undo was designed with this sort of thing in mind. Instead of working through the operation queue like normal people, it simply switched repeatedly between previous state and current state - the idea being that you'd make a change that you weren't certain of, then press the key repeatedly to see before and after. No need to think. Thinking isn't appropriate here anyway. Just let your eyes look at what they're seeing.)
