inspired by the discussion of glitch sounds which are sometimes appealing in the above thread, I unearthed some of my own deliberate glitch images and sound files., and wanted to encourage everyone else to share if they have any deliberate or accidental glitch art, or make some now and share it!
I personally got into doing this after a conversation with my late friend Robert Wood, who did a lot of forced glitch visual art; I think he had hundreds of unique prints done in this way, and you can see a couple of them behind him in the linked article.
here are a few of my experiments from 2008 (nearly 10 years ago! ahhhh ). these were done by opening jpeg files of photos I had taken (plus one of my mom when she was young) with a text program (Textedit on Mac, if I recall correctly) and copying, pasting, and otherwise generally messing with the raw code. I had my best results when I left the first and last 5-10% or so of the code alone, as it seemed to be important to then be able to resave and open the file in a photo program. I believe I also had the best luck reopening glitch image files in Photoshop, which seemed more tolerant of weird code, and then resaving from there and getting full compatibility with any image software. none of these were edited in any way besides manipulating the raw code.
this is definitely the sort of thing that is best done in large quantities - you’ll get a lot of ugly or just totally nonfunctional files, but then you’ll start to pick up little techniques that you can sort of control things (but only sort of). you truly do not (should not?) need to know what you’re doing, in my opinion.
I also did some audio experiments like those that @trickyflemming mentioned in the W/ thread, but I was mainly editing the code from existing audio files in the same way as the images above. none of my old audio ones are particularly interesting, but maybe you have some that are?
