So my attempt at a video. I've been taking photo's every week of a key-fob of a cassette. The black paint started to come off really quick, and it's nearly all off now. Sped up a recent track (Cavernous) so it fit with the photos merging. So it's just photo's of a disintegrating tape. And then reversed, so it loops over a few minutes.
