One of the things I appreciate about HN is that discussions often acknowledges the pioneers. Way back in the early 1990s Eric Begleiter started Dimensional Foods to commercialize edible holographic technology. He gave a memorable demo at Thinking Machines Corp. where, in addition to rainbows from diffraction sheet molded foods, he showed some simple rendered 3D scenes floating in chocolate illuminated by a slide projector. Very impressive at the time when he broke off a chunk and ate it. The short-term idea was to give a rainbow sheen to breakfast cereals, but I think longer term there was talk of using holograms to distinguish and layer information on medicines. Made quite an impression at the time.
