This is a script for windows ( using git-bash terminal and with imagemagick installed) to glitch images in batches of 3 and then makes those images into a single gif - it copies the original source files into a folder called originals to keep them safe, then moves each batch of three files into the frames folder , glitches them then creates a gif from them then dletes the original images - it does this until images in directory where script is running from are gone !! A work in progress use at your peril .
