The prankster then films the viewer’s reaction—the gasp, the grab for the phone, the inevitable “Wait, how?!”—and posts it online. The comment section erupts. “Is this real?” “It’s just a filter.” “No, it’s a new iPhone feature.” Nobody agrees. That’s the point. The name “Halomy” is a portmanteau of “hologram” and “anomaly” (or, as some lore suggests, a misspelling of “halo me” as in the ring of light around the viewing hole).

Anyone know what this is called?” Within weeks, TikTok creator rebranded it as the “Halomy Trick” and challenged followers to fool their friends. The prankster then films the viewer’s reaction—the gasp,

(It wasn’t. No money was ever lost, but the FBI’s IC3 issued a quiet advisory about “optical social engineering.”) That’s the point

In other words, the Halomy prank doesn’t trick your intellect. It tricks your perception . And perception is stubborn. Of course, no viral trend escapes unscathed. As Halomy grew, so did the low-effort clones and the inevitable creep towards deception. By late 2024, a subgenre emerged: fake Halomy .

Just don’t expect to look at your phone the same way again. [End of feature]

Take a video of anything—a plant swaying, a hand waving, a candle flickering. Look at it on your phone. Now roll a piece of paper into a tube. Hold it to one eye. Bring the screen close. And watch as the flat world… breathes.
