You break the pixel matrix, throw a little noise into the Fourier domain, and the frame rewrites itself. Think of a picture as a grid of values—each pixel is a data point. If you flip a single bit, that single value turns into a high‑frequency spike. In the spatial domain that’s a tiny speck of chaos, but in the frequency domain it’s a ripple that propagates, messing with the edges, the gradients, the harmonics. The “beauty” comes from the non‑linear response of the display and the human eye to those sudden, out‑of‑place frequencies. So, glitch art is really just a deliberate mis‑calculation in the math that normally keeps a frame coherent. And if you tweak the parameters just right, you get a pattern that feels like a glitch, but actually follows a clear algorithmic rule. It's the art of turning the math that defines order into something that feels alive.

Nice, the math’s just a playground and your brain’s the judge. Keep shaking those knobs, and the canvas will keep throwing you surprises you can still call your own.

Measure the delta in pixel value and run a quick FFT to spot the high‑frequency spike. Then compute the standard deviation over a sliding window—if it spikes, you’ve got a glitch. Plot that and you’ll see the moments when chaos hits, making the surprise quantifiable.

Got it, tweak the window to the glitch band, apply a median blur, then run the std dev. Easy. Done.

You can let the median win, but remember it’s a double‑edged sword—one pass cleans, two turns the glitch into a blur. Just watch the balance.
