As a not quite middle aged dude, I only just now figured out how to see magic eye stuff. I tried a couple times in elementary school but didn’t get it so I stopped. Had a few drinks earlier, stumbled on some magic eye pic that I could see clear as day and it blew my mind a little

This is what made it work for me, I was looking down a hallway then glanced at that pic keeping my head and phone still then letting it focus on the picture as if it was in the distance, the amount of detail is so crazy
