never been able to see something 3D out of those garbled images

to the point i'm thinking it's a global hoax, are there any easy exercises somewhere ?

haha, best issue ever ;-)
Of course it's working, I can see the shapes but that requires a little work on the eyes' muscles.
Back then, I had books filled with those stereograms, and usually they also gave a way to train your eyes to focus differently, but I don't think that all people can do it (my mother never managed to see them for instance).
Maybe try those 2 methods : http://www.hidden-3d.com/how_to_view_stereogram.php

Don't concentrate on the image. Try to zone out/daydream while looking at it so that your vision is "beyond" the image. Like the image is a window and you're looking beyond that to see something outside. The really hard ones though, it helps if I cross my eyes just a tad and blur my vision using the same approach I just mentioned.

Yeaeayeayeaeya ! got it ! for the first time ! I see my mistake now - i always expected the effect to "bump" out of screen towards me, but in fact it's like it was going inside or behind the monitor.
Now... i sent a screenshot to my mother but she says she doesn't see squat.

joking, thanks for the links

Haha! Yeah, my point: mothers can't see them ;-)

well my joke would have been about trying to take a screenshot of the 3D effect itself, but i'm not so good at joking in english.
Seriously i think i succeeded thanks to http://www.vision3d.com/3views.html
and especially http://www.vision3d.com/methd03.html (reflection method)

Woo! Haha, my mother can't see them either.

The calibrator dots at the beginning of this video are pretty helpful: https://www.youtube.com/watch?v=2AKtp3XHn38. I was thinking it could be cool to add a similar feature to this project.

Came here to file this exact issue (including global hoax theory). Was not disappointed.
