Based on a technique called “Pepper’s Ghost” Robbie Tilton shows us how he created a Hologram-like effect using a reflective prism, a technique which basically reflects an image off a reflective surface to create an illusion of a floating 3D object. The “Pepper’s Ghost” effect was first designed with only one reflective surface being used but Robbie decided to take it a step further and use four reflective surfaces giving it a more realistic look and feel. No longer bound by looking at the image from one angle you are now able to view it from multiple angles giving you the ability to walk around the display and with a little work you can also have the display turning giving it an even more futuristic feel.
