Advances in display technology are simply amazing. I hope to see holographic display units so common place that they are used in cheap kids toys like and LCD would be used today.

The new material is comprised of photorefractive polymers. These chemicals have photoelectric properties that make them well-suited to storing the optical interference patterns used to produce holograms. When a photorefractive polymer is exposed to a pattern of bright and dark areas, electrons are released from the areas exposed to high-intensity light and migrate to areas that are darker. Once in place, the electron-rich areas diffract light differently from the electron-poor ones, allowing the original interference pattern to be reproduced when the material is exposed to light
