How This Hologram* Breaks Physics

11 min video5 key momentsWatch original
TL;DR

What you think is a hologram isn't one—most famous 'holograms' are 2D projections on transparent screens, but the Voxon VX2 uses spinning LED panels at 900 RPM to create an actual volumetric 3D display that feels like the real deal.

Key Insights

1

Interference patterns, not 2D screensReal holograms use interference patterns created by split laser beams to record depth information, but most famous 'holograms' like Miku at concerts are just 2D images on transparent screens.

2

7,200 updates per second via USB 3.0The Voxon VX2 spins at 900 RPM and must update its LED panels over 7,200 times per second to display 3D video at 30 frames per second—all through a single USB 3.0 cable.

3

Wireless induction eliminates cable messThe device uses wireless induction for both power and data transfer to the spinning panels, avoiding the cable tangle problem that would destroy the display.

4

Defeating physics through engineeringAluminum frames and precisely engineered laminar airflow inside the dome prevent LED panel flexing at high speeds, which would warp the image.

5

360-degree communal viewingThe VX2 is fundamentally a digital campfire—the first display where multiple people can stand around it and see 3D content from 360 degrees simultaneously.

Deep Dive

What Isn't a Hologram (But You Thought It Was)

The Studio opens by demolishing a common misconception: almost every famous 'hologram' you've seen is a fake. Miku at Meikofest? Rear projection on a transparent screen. Pac-Man at Coachella? Pepper's Ghost illusion. The Razer display at CES? Likely a transparent OLED or miniLED screen inside a tube. None of these are actually holograms, and more importantly, none of them are 3D—they're 2D images on transparent surfaces that flatten completely when viewed from the side. The confusion exists because there's a gap between what a hologram technically is and what people imagine a hologram to be. A real hologram, according to traditional holographers, is something like a credit card with a reflective surface that creates a parallax effect as you move it—no screens, no projectors, just physics.

How Real Holograms Actually Work

Real holograms capture depth information using interference patterns, a technique that relies on light's constant speed. To create one, you split a laser into two identical beams. One bounces off the object you're scanning, the other goes straight to holographic film. Where those beams meet, they interfere with each other, creating patterns based on the exact timing of the reflected light. That interference pattern gets stamped into metal, creating tiny ridges that reflect light in the exact same way the original object did. When you tilt the hologram under light, you get a 3D parallax effect as if you were moving around the object itself. The catch? Real holograms are underwhelming. They're flat surfaces that create a fake window effect, not the floating Princess Leia 3D apparation everyone imagines. The Studio acknowledges this is physics-heavy material and points viewers to 3Blue1Brown for a deeper explanation.

The VX2: A Volumetric Display That Actually Works

Instead of a true hologram, the Voxon VX2 is a swept volume display using persistence of vision—the same principle that makes animation work. By showing 2D slices fast enough, your brain stitches them into a continuous 3D object. The device spins at 900 RPM, equivalent to a car wheel on the freeway. At that speed with 480 slices per rotation, the LED panels need to update over 7,200 times per second to display 30-fps 3D video. This is where engineering complexity explodes. The entire display connects via a single USB 3.0 cable—no Thunderbolt, no HDMI—so the graphics engine must be absurdly efficient. The creator was written by someone who optimized the Duke Nukem graphics engine in the '90s, bringing that same creative problem-solving to modern 3D rendering.

Engineering Against Physics Itself

The real innovation lies in defeating the laws of physics through clever engineering. At 900 RPM, the LED panels want to flex, and any deviation throws pixels out of alignment, warping the image. Voxon solved this with an aluminum frame sandwiched between the LED panels to keep everything rigid. But they went deeper—they engineered the air inside the dome to flow in laminar patterns matching the display's rotation, eliminating turbulence that could destabilize the panels. The data and power problem was equally complex. Running cables to spinning panels would create instant wire spaghetti, so Voxon developed wireless technology: inductive charging for power and wireless data transfer. These aren't just clever tricks; they represent fundamental problems most engineers wouldn't even consider solving.

What It Is, What It Isn't, What It Could Be

The VX2 isn't the highest-resolution display ever made, nor does it have perfect color accuracy—it flickers slightly in person. But it's genuinely revolutionary as the first digital campfire, a 360-degree display where multiple people can gather around and see 3D content together simultaneously. The device feels like a throwback to garage-era innovation; Voxon started that way, like early Apple or Compaq. The Studio and Marquez debate whether to judge the technology on its current limitations or its potential. Marquez uses a car analogy: you wouldn't criticize a McLaren P1 for being useless in a world with no roads. The core tension is that the display exists before the content does. As a pure engineering achievement, it's extraordinary. As a consumer product with actual use cases, it's still searching for its purpose.

Takeaways

  • Almost every famous 'hologram' you've seen—Miku, Pac-Man, Razer displays—is actually a 2D image on a transparent screen, not a true 3D hologram.
  • The Voxon VX2 solves the volumetric display problem by spinning 480 LED slices at 900 RPM and updating them 7,200 times per second through a single USB 3.0 cable using a hyper-optimized graphics engine.
  • The real innovation is the engineering: wireless power and data transfer, aluminum frames, and laminar airflow all combine to prevent the physical flex and vibration that would destroy the image at such high speeds.
  • The VX2 represents a paradigm shift in how displays could work—not as screens you look at, but as 360-degree communal objects multiple people experience together.

Key moments

0:10The Core Deception

But technically, it's not a hologram. Everything that you think is a hologram actually isn't a hologram.

0:46What Real Holograms Do

The way real holograms work is actually really interesting. And it all comes down to capturing depth information and then recording it using these things called interference patterns.

5:00The Processing Nightmare

If it rotates at 15 times a second and loads about 480 slices into a rotation, that means in order to play a 3D video at 30 frames per second, you need to update the panels on this thing over 7,200 times per second.

6:45Defeating Physics

When you spin an LED panel at 900 RPM, it really wants to flex. And what happens when it flexes? Those individual LEDs will be at a slightly different place than they're supposed to be, and your image gets warped and jumbled again.

9:54The Digital Campfire

This thing is really the invention of the digital campfire, the first narrative experiential display that people can stand around and see each other and see the content from 360 degrees.
