Drag anywhere on the image to aim the slit by hand.
Re-renders the whole frame every tick from a rolling buffer of past frames — a live, warped window into the last few seconds, not a smoothing filter. Not available in Strip — it has no fixed time depth.
Feathers the edge of every slice as it's painted, so the seam between one instant and the next blends instead of stepping. Works in every mode.
Many years ago I had an iOS app that made slitscans, and I had a lot of fun making hundreds of them with it. This design takes slitscans further, with more scan modes and effects. A work in progress.
