An FFGL effect that sends your clip as a Level 1 teletext page: 40 by 24 cells of 2 by 3 mosaic sixels in eight colours, where every colour change is a control code that costs you a cell. An optimal encoder plans each row, the page arrives a few rows a field and tears between rows, and bit errors land the teletext way: one bit blanks a cell, two bits corrupt a mosaic, and a row never moves.
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.
