I cropped the pictures, and rotated Ron's picture by 0.2° (it wasn't perfectly vertical), so as to line them up on the lighthouse's door:

Open both in 2 tabs on a computer, and quickly alternate between the 2 tabs, the 3D effect is quite visible because of the perspective differential :-)

Works well with cross-eyed viewing too, with the images side-by-side:

This doesn't work on mobile because jsfiddle has that little overlay in the top corner covering most of the picture

It's not so bad in landscape mode for me, try that perhaps?

You can delete the overlay using dev tools.

In Chrome, I hit F12, selected the overlay in the DOM and deleted it.

I doubt the person you replied to has F12 available on their mobile device.

This is great! The waves get 3D.

Woah, thanks for this. I've always known about cross eyed 3d it but was never able to make it work... Until I tried that image for a minute or two and then bam, something clicks and my eyes lock in!? And now I have to make an effort to unfocus the merged image. What kind of sorcery is this?

Why does there seem to be a skew though?
