logical evolution of the long-exposure video-to-image processing i was doing a while back, now doing video-to-video processing with a decay factor

here's about 10 minutes of haneda airport (tokyo) sped up and processed to produce these delightful light trails

@luna a long time ago I tried my then-relatively-new Sony NEX-3N (which I still have, or at least have back after a long time away) handheld video in Covent Garden at the end of a day, and it was too dim a light to give normal exposure so it seems to have given me video comprised of time exposures. It was really to test video sync to the mid-side mic I was using, but I became very much intrigued by this visual effect, especially all in camera (and hand-held at that!).
