Project Hologram-Like Images from Your iPad or Tablet This inverted pyramid made of thin, clear plastic creates a fantastic illusion that allows you to create what LOOKS LIKE a hologram using ANY iPad or tablet. You'll find dozens of 3 dimensional moving images to project such as lightning storms, the rotating Earth, flittering butterflies, swimming jellyfish, exploding fireworks, the flaming Sun and many, many more. The PepperGram projector works because by darkening the room and using a bright 3D video, the 4 sided pyramid (made of semi-reflective, semi-transparent material) produces several such images so you can view a realistic image in 360 degrees. The plastic used to make the PepperGram Projector is super thin - why? To prevent the formation of a double image. So if it's not a hologram, what is it and how does it work? A hologram is a specific kind of photograph that captures light that has been scattered from multiple surfaces of an object so the image produced appears three-dimensional. Creating a hologram requires a laser, a beam splitter and special holographic film. The "DIY Hologram" does not require any of that. So, what is it? What's going on is a variation of an old illusion technique used in theaters and haunted houses known as Pepper's Ghost. It was made famous in 1862 by one John Henry Pepper. But the very first mention of the effect was made long before that, in the 16th century by a Neapolitan scientist, Giambattista della Porta who is also one of the pioneers in optics.
