Does the effect work with an animated depth image?

I always have a hard time with these. I get the 3d effect but can never figure out the image. I suspect based on reading some theory that I am viewing them cross eyed instead of slack eyed. But have no idea how to do it the other way around.

Update: it does, I found a youtube video, still cant resolve it however. https://www.youtube.com/watch?v=IZpsbQMQFBs

I have always crossed my eyes since the days of Magic Eye books, and could reliably "see" the image but it was always reversed (seemingly going INTO the page). It wasn't until this article that I realized I could go "slack eyed" as you call it. Now the images pop OUT of the page instead of recede into it. I wish I could rewind 30 years and tell my younger self how to do it.... I would have enjoyed those books so much more.

I flip the lid mostly closed on my MacBook and stare off at something across the room past the laptop. While still staring at that thing across the room I bring the display lid up in front of my gaze.

I can only see them as cutouts. They never pop out at me.

Linked video - these are some of the coolest I've seen in a long time: https://www.youtube.com/watch?v=NmRfVoiFDu4

The nested petal thing at 45 seconds.

This is a good one — probably came up on an earlier HN post:

The video just animates the surface picture, and swaps between different depth maps. But otherwise the depth maps are not animated, alas.

This one https://managore.itch.io/stereogram (link from another comment) actually animates both.

Thanks for sharing that video, worked perfectly for me. Although watching videos with this effect is kinda headache inducing after a while, at lesst for me.
