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.
More troubling was the exploit. Scammers realized they could overlay a Halomy-style video onto a payment confirmation screen, tricking users into thinking a 3D hologram was authorizing a transaction. (It wasn’t. No money was ever lost, but the FBI’s IC3 issued a quiet advisory about “optical social engineering.”) halomy prank
The Halomy prank hijacks that system.
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
Most viral tricks crumble under explanation. Once you know the “candle and string” trick or the “magnetic spoon” illusion, the magic dies. But with Halomy, even when you understand the parallax principle, the experience doesn’t fade. Tell someone, “It’s just your brain misreading motion cues,” and they’ll still press their eye to a toilet paper roll to watch a TikTok of a dog running through leaves. Hold it to one eye
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). The trick itself is ancient in optical terms—it’s a variation of the pinhole effect or the Wheatstone stereoscope from the 1830s.
Here’s how it works in practice: The prankster films a video using only one lens (usually the rear camera of a phone). They then ask a friend to look at the phone’s screen through a small hole—a rolled-up piece of paper, a cutout in a card, or even just a gap between their fingers. When the viewer closes one eye and peeks through the hole, something strange happens. The brain, deprived of binocular depth cues, suddenly interprets the motion of the video (the slight shake of the camera, the panning movement) as real spatial depth .
