Instead of having the pixels on the letters scrolling down, wouldn't it also work if the pixels were simply re-randomized every frame?

#192https://gist.github.com/jncornett/d7cb397ce3ceff268a0ee1b86f... On iPhone: screenrecord. Take screenshots every couple seconds. Overlay images with 50% transparency (I use Procreate Pocket for this part)
A single photo is good enough as long as the exposure time is long enough to capture the motion blur.
If I had another camera then yes, that would have been easier. In my case I only had the one mobile device and I don’t think screenshots support long exposure.

#193Is this supposed to show something? All I am seeing is a static noise generated on a moving background towards the bottom. No text.

#194You can take TWO screenshots, moments apart, open in GIMP, paste one over the other and choose any one of these laying modes: Lighten, Screen, Addition, Darken, Multiply, Linear burn, Hard Mix, Difference, Exclusion, Subtract, Grain Extract, Grain Merge, or Luminance. https://ibb.co/DDQBJDKR

#195This should have an epilepsy warning. Or something of that kind. It certainly made me feel sick.
This feels like when I had the spins in my college years.

That's a real method: https://digital-photography-school.com/taking-photos-in-busy... https://petapixel.com/2019/09/18/how-to-shoot-people-free-ph... But it only works well if the crowds move out of the way reasonably quickly. If we're taking about areas packed with people all blocking a certain area, and you need hours of shots, the change in ambient lighting over time will have negative effects on the end photo.
Ah, that's the method indeed! Thanks!
There's an analogue method too - just do a very long exposure of a busy street. There is so little reflected light from people (relatively speaking) that it barely registers on the film/sensor, hence they are 'invisible' in the final shot. That's why old street photos are sometimes empty of people, because both lenses and film were slow, leading to long exposures.

#199I have no idea about anyprogramming at all, but i tried to make chatgpt make a wolfenstein-like game using this concept. It doesnt work but perhaps someone will be interested in the concept: https://pastebin.com/SKAnBPMg
