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
I’m pretty sure the scene from Mallrats was based on me. I stood and stared at those at the mall for days and could never see them. Finally one day - 20ish years later it finally clicked and now I can see them.
