Chocograms

I recall, as a child, being mesmerized by a holographic cover of National Geographic. I think it was the November 1985 issue.

Now we have chocolate holograms. The images are, reportedly, created by Morphotonix by using molds to microscopically alter the surface of the chocolate to create the holograms. As an added benefit, the system needs chocolate with small crystal structures (ie, not grainy) in order to create the correct textures.
