Building Generative Glitch Art Tools

• knuthsat 5y ago
  I remember having such a nice discovery of "glitch art" when I was writing my own quantization algorithm (discrete cosine transform [and inverse]) and I had a bug but got nice looking outputs, like this one: https://i.imgur.com/LMjg40v.png https://i.imgur.com/LMjg40v.png Not sure I remember what the bug was (probably some overflow/clipping issues when dealing with 8 bit numbers) but the original image (above) was unprocessed frame from a movie (I don't remember which one). Once the bug was fixed, there was little difference (except for the blocking effect of quantization). Was quite surprised how such a small bug creates such drastic visual difference.

  Reminds me of this tool that lets you corrupt jpeg files: https://snorpey.github.io/jpg-glitch/ https://snorpey.github.io/jpg-glitch/

    Wow, that is amazing. Thank you for creating it and sharing. I'd ask you how it's so, so fast but I doubt I'd grok the answer.

    I personally use Glitch Lab for Android that has a sick depth of use, loving it.
