Hologram Shown Off In Hong Kong

Holography is the science and practice of making holograms. Typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics.

The hologram itself is not an image and it is usually unintelligible when viewed under diffuse ambient light.

This is a Hologram made from two spinning rods and it was shown off at a convention in Hong Kong China.
