Does anyone know of any good resources for approximating more (for want of a better term) analog glitch effects in code? The VHS and slitscan presets in Glitché[0] got me wondering how one might go about producing the kinds of effects/artifacts commonly seen in scanography[1][2] and VHS manipulation[3][4].
