* time, space, stacking, slicing, scanning, etc 

“Slitscan imaging techniques are used to create static images of time-based phenomena. In traditional film photography, slit scan images are created by exposing film as it slides past a slit-shaped aperture. In the digital realm, thin slices are extracted from a sequence of video frames, and concatenated into a new image.”

This particular slitscan provides some slightly configurable scaffolding around ffmpeg (based on a blogpost from [[http://oioiiooixiii.blogspot.com/2017/11/ffmpeg-temporal-slice-stacking-effect.html][oioiiooixiii]]) and is intended for non-realtime rendering at various resolutions. it's neither first, nor last. it's not especially interesting, educational or efficient. just another cloudform in the endless space of possible implementation…
