I made holographic chocolate!

Way easier than I thought - and it’s 100% pure bittersweet, no coatings. When you catch the light at the right angle, it’s mesmerizing. pic.twitter.com/HFi0K5IGSG
AI design genius and Renaissance woman Janelle Shane describes it as "holographic." I'm not sure if that is the correct term. At a bare minimum, it's shiny. I'm going with iridescent because of the visual effect as you change your perspective.
Shane followed these Instructables instructions by jellmeister, which use diffraction grating sheets to add the visual impact to chocolate. Shane explains that the texture of tempered chocolate is so fine that it can hold the sheets and permit diffraction with good lighting. Read her whole Twitter thread to see optics experiments with it.
