Why is "Lippmann plate" trending?

Wikipedia Overview

Lippmann process photography is an early color photography method and type of alternative process photography. It was invented by French scientist Gabriel Lippmann in 1891 and consists of first focusing an image onto a light-sensitive plate, placing the emulsion in contact with a mirror during the exposure to introduce interference, chemically developing the plate, inverting the plate and painting the glass black, and finally affixing a prism to the emulsion surface. The image is then viewed by illuminating the plate with light. This type of photography became known as interferential photography or interferometric colour photography and the results it produces are sometimes called direct photochromes, interference photochromes, or Lippmann photochromes. In French, the method is known as photographie interférentielle and the resulting images were originally exhibited as des vues lippmaniennes. Lippmann won the Nobel Prize in Physics in 1908 "for his method of reproducing colours photographically based on the phenomenon of interference".
