An FFGL effect that treats your clip as the print on a trading card and puts a holographic foil under it: the holo window behind the art, the reverse holo round it, foil over the whole card, or foil only where the ink is light or dark. None of it's painted on. Every pixel is a little diffraction grating under a lamp, so the colours are the ones a grating really throws at that angle, they run through the spectrum as the card tips, and the ink on top filters them the way printing ink does.
This demo runs the plugin's shaders and a port of its CPU half in your browser, so it needs JavaScript and WebGL2. The plugin itself, its source and its downloads are on its repository.
