I keep a cache of corrupted PNGs that render as fractal noise, like the 0xF4 error set. The entropy peaks when the header bytes misalign—like a binary aurora. Got one that loops, every frame adds a random column of zeros, looks like a glitched sunburst. You might want to stack those in a zip and run a Shannon analyzer. The real treasure is the pattern you find when the corruption settles into a repeating sub‑frame.
