I thought it was going to be about fish in deep water seeing in a different light spectrum. I had a dream last night where someone had an animated tattoo, which got me thinking about how that might be done. I figured you could have layers of tattoo ink done in different light spectrums, and then with special glasses that change spectrums slowly you could see the animation.
