My time has come!
The above stereographic image is for cross-eyed viewing (most stereograms are wall-eyed, so you may need to put your finger in front of your screen until this one comes into focus)
This is an image of Honolulu, Hawaii, published by NASA. Note Diamond Head (the volcanic crater) in the south.
Here are some other stereopairs published by JPL:

Wheeler Ridge, California

Mount Saint Helens

Ah, thanks for the edit. I still think that these have greater value from a scientific perspective, but I do also have a collection of many stereo images that I could post here for you! They’re MUCH older, though:
Sorry for the poor quality here! It’s difficult to take nice scans of these since they’re curved with age. OH, also, these are wall-eyed, not cross-eyed.
The third from the end to the beginning is quite spectacular showing the effect. I’d put that one first, honestly.
Thanks for the additional examples!
Is the last one (lion statue & building) a reprojection? I didn’t see depth (or parallax) in the background, just between the lion and the building.
Oh, that is SO COOL! Do you have any more anatomical pictures in stereo?
I agree with the general sentiment, though I believe that the value of these images from the perspective of scientific appreciation outweighs traditional Magic Eye images. I remember, ten years later on, how my professor for the geology intro course let us see images taken over Germany by British intelligence, and you could literally see how they used the stereography to find missiles, because you’d be looking at a bunch of flat terrain and then bam, there’s a weird thing poking up out of the ground near that farmhouse. Then, she showed us some of these, and showed us how you could compare the topography in these to those on the topo maps. From a “wow” factor, not everything is going to be as flashy as a Royal Institution Christmas lecture, but this is what science looks like.
At my work, we maintain computers that use Nvidia glasses to view stereo images of protein structures.
Nvidia doesn’t support them anymore, and there was an email thread that was forwarded to us by the lab manager of some scientists discussing the issue. One of them suggested to the others that they could just cross their eyes and see the images that way instead of using the glasses. Funny stuff!

Cool effect. For me, it only works on a screen where the white dots are roughly the distance of my eyes. So not on a phone.
