An FFGL effect that loads your clip the way a ZX Spectrum loaded a screen: in screen-memory order, at the baud rate, monochrome first and colour last, with the border striped by the loading signal itself. It's a transition built from an address order rather than a shape, so the venetian-blind thirds nobody designed are just where the bytes go.
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.
