This simple little device is way cooler than it has any right to be. An inverted pyramid made of light, thin, clear plastic creates a fantastic illusion that allows you to create what looks like a hologram with nothing but any cell phone and some videos from YouTube.

Just search for face pyramid holographic video for lots of cool video images.
The plastic used to make the PepperGram Projector is super thin to prevent the formation of a double image.
Pepper’s ghosts are created via a sheet of material that is both semi transparent and semi reflective in nature; usually either glass or plexiglass.

Generally, when you place an object on one side of the material, most of the light that bounces off that object passes (is transmitted) through.
