It’s as simple as that to transform your ordinary device into an out-of-this-world experience. But how does it work?

How does the hologram work?

Optics are all about the manipulation of light with lenses, mirrors, and splitters. Light can bend, get absorbed, and reflect. When watching the video on your device, the light being emitted from the screen is mostly aimed straight up. Once the pyramid is added, the plastic that hangs over the images acts as a splitter. It allows light to both travel through it and get reflected at the same angle at which it enters. The four different sides will add the four images into the center, creating what looks like a 3D hologram!
