The Halomy prank hijacks that system.
And that, perhaps, is its deepest magic. Not the illusion itself, but the moment of shared wonder. Two people, one hole, and a flickering rectangle of light that, for just a second, becomes a window into another world.
But its digital rebirth began in late 2022 on Reddit’s r/blackmagicfuckery. A user posted a clip of a hand moving behind a phone screen, captioned: “Found this weird 3D effect. Anyone know what this is called?” Within weeks, TikTok creator rebranded it as the “Halomy Trick” and challenged followers to fool their friends.
If you’ve scrolled through TikTok, Instagram Reels, or YouTube Shorts in the past year, you’ve seen it. A person holds up a smartphone. On the screen is a photo of a lush green forest, a glittering cityscape, or a celebrity. Then, they place a second phone—or a piece of paper with a hole—between the camera and the viewer’s eye. And suddenly, the flat image explodes into a 3D diorama. Trees have depth. Buildings have distance. The celebrity looks like a hologram standing in your living room.
“It’s not about believing it’s real magic,” says Dr. Maya Ferns, a cognitive psychologist studying viral illusions. “It’s about feeling the illusion override your knowledge. That dissonance—‘I know this is a flat screen, but I see depth’—is more satisfying than actual magic.”
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.”)
Creators began using actual 3D-rendered videos or multi-camera rigs to simulate the effect, then pretending it was the simple pinhole trick. When viewers tried to replicate it with a piece of paper and a friend’s phone, they failed—and the creator would comment, “You just didn’t do it right.” Trust eroded.
