like the deepfrying meme (go to https://www.youtube.com/watch?v=svBMtxcBzO0 if you don’t know what deepfrying is)
Not my thing, had to look it up
“Deep Fried Memes are a style of meme wherein an image is run through dozens of filters to the point where the image appears grainy, washed-out, and strangely colored…”
I would try the gimp_gmic_qt plugin www.gmic.eu and in the testing section, experiment with the Joan Rake filters. Maybe Auto Gnarl followed by JFIF effects Plenty combinations of filters to play with.
