Some people can't see the upside-down plates. This one might work for them - it's the same uncropped image rotated ninety degrees both ways.
People are used to illumination coming from above - not from below; so when the scene is illuminated from below, one's brain is inclined to flip the image inside-out to make it better match with the 'usual' illumination.
Also if you don't want to shake your head, step back far enough from the screen so you're not resolving the lines as well and the secondary image will show through.
The effect isn't so strong on my desktop monitor, but when I've seen this pic on my phone, it straight-up looks like a full-color photo unless I zoom way the fuck in. It's especially noticeable in the people's skins, I don't see gray at all, I see a for real human-style flesh tone.
First time I saw it was on a smaller screen, and although I could see the grid lines, I still believed the photo underneath was a normal colour one - until I read the spoiler and checked.
Of course, the colour receptors in our retinas are much more spaced apart than the non-colour ones, and there are very few colour receptors away from the centre of our field of view - so our brains are always dealing with high resolution monochrome images with a much lower resolution colour overlay - this image just helps reveal that in a somewhat surprising way.
If it's not working for you, try squinting a bit, or standing further away from the screen.
There's also a link right in that picture, so instead of myself running off at the mouth about luminance, chrominance, JPEG and all that other jazz, linkypoo
Do you get the same effect if the guy at the end isn't running?
Yes. To see, just cover up the part of your screen where the running guy is. (You don't have to cover much of the screen, because the guy doesn't travel very far!)

If you get far enough away from it to lose the edges that give the apparent movement it will suddenly look like a blinking static image.
I do wonder how much the characters play in it, like how far from the 45 degree angle can the apparent motion be moved On the stairs figures before they don’t feel like they connect anymore.
