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.
