An FFGL effect that does slit-scan photography to your clip, once a frame: the phone filter that gives everyone a three-foot chin, Trumbull's Stargate corridor from 2001, the Doctor Who title tunnel and the Star Trek warp stretch. None of it's drawn. Each is one long exposure taken while something moves, and the perspective, the lean and the glow at the far end are what a slit, a dolly and an open shutter give you.
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.
