An FFGL effect that runs your clip through a xerographic engine up to eight times a frame, each copy made from the last: optics, an auto-exposure that throws the background away, a steep photoconductor, development that follows the electric field above the latent image rather than the image itself, a toner supply that runs short, and a drum whose defects repeat down the page. Greys collapse to paper or toner, wide solids go hollow while thin lines print full, the page runs out part-way down, and the skew drifts a bit further with every generation. Much like the office copier, minus the paper jams.
This demo runs the plugin's shaders in your browser, so it needs JavaScript and WebGL2. The plugin itself, its source and its downloads are on its repository.
