Feel free to reblog without tutorial if ya want:
Databending .gif animations like this is one of the easiest things you can do in Audacity, it just takes a little finesse. Open up the .gif file in Audacity (A-law, 1 channel, little-endian). Now I want you to zoom in as close as you can somewhere in the middle of the file, just stay away from the beginning really. Now I want you to select the draw tool. Select one the samples, just one of the little dots at the end of two intersecting lines, and move it. Maybe be bashful at first, move it just a little bit. Now save the file (A-law). Open it up and voila. You can definitely edit more than one sample, but the point is you can’t go wild cutting and pasting/using filters like you do on other formats. Now sometimes these files won’t open up in an image editor but they WILL open up in Irfanview (a must have application for glitch artists). So now you can use CamStudio or LiceCap or some such thing to capture your databent gif.
