What if your phone could project real 3D?
🎥 Here’s how this mind-bending trick works:
	•	Place your smartphone inside a spinning rig with a narrow slit.
	•	The slit lets you see only a thin slice of the screen at once.
	•	As the phone spins, each slice comes from a slightly different angle.
	•	When both the phone’s image and the rig rotate at the same rate, your eyes blend the slices together—like a 3D sculpture made of light.

It’s the same principle as a persistence-of-vision display, but extended into three dimensions. Engineers call it a volumetric display.

🧠 Bonus: Adjusting frame rate and rotation speed changes the depth clarity. Too slow → flicker. Too fast → blur.

Would you try building one? What would you display first—DNA helix, planet, or logo?
