The use of "qR cOdES®" appears to have developed from a previous system of colored "bar codes" algorithmically generated from the same types of invariant knots, but with less resolution. I suppose the "BAR coding" could be visually interpreted like resistor values in assembling or diagnosing circuit boards. However, what they're doing is art. They are algorithmically generating beautiful artwork that can be admired for its colors, labyrinthine complexity, near-symmetry, shapes and analogy to real-world or theoretical knots. https://en.wikipedia.org/wiki/Celtic_knot https://en.wikipedia.org/wiki/Celtic_knot https://en.wikipedia.org/wiki/Tartan#Legal_protection https://en.wikipedia.org/wiki/Tartan#Legal_protection https://en.wikipedia.org/wiki/Fractal_art https://en.wikipedia.org/wiki/Fractal_art https://en.wikipedia.org/wiki/Moir%C3%A9_pattern https://en.wikipedia.org/wiki/Moir%C3%A9_pattern They have not proposed any way of scanning or processing the art back into data, and in fact they point out that printing, display, visual inspection or comparison may not produce mathematically accurate results, so this is representational art that they can emblazon on their mugs, sugar cookies, tee shirts, and sell on Etsy. https://en.wikipedia.org/wiki/Psychedelic_art https://en.wikipedia.org/wiki/Psychedelic_art In fact Dr. Bar-Natan has done a lot of work in perceptual art that looks like another thing: https://www.math.toronto.edu/drorbn/papers/PDI/ https://www.math.toronto.edu/drorbn/papers/PDI/ But he calls it "PDI" and not "Magic Eye™" The fault of naming "qr codez®" doesn't rest solely on the latest researchers, but they are "standing on the shoulders of giants" who generated "bar c0des", which may have started with some colored pencils, a cocktail napkin, and 3 pints in a pub.
