You 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
Is it possible to modify the webpage to make the pattern of the text go down and the pattern of the background do up?

#173https://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.

I've found taking two screenshots and adding them as separate layers works well, and then setting one as Difference, and then tweaking the opacity.
Here it is in Pixelmator Pro: https://i.moveything.com/299930fb6174.mp4

> You can take TWO screenshots, moments apart, open in GIMP, paste one over the other and choose any one of these laying modes: You actually don't need any image editing skill. Here is a browser-only solution: 1. Take two screenshots. 2. Open these screenshots in two separate tabs on your browser. 3. Switch between tabs very, very quickly (use CTRL-Tab) Source: tested on Firefox
What does that accomplish? You can just read the web page as-is...
Are you going to share your two screenshots, and provide those instructions, with others? That seems impractical.
Video recording is a bit less impractical, but there you really need a short looping animation to avoid ballooning the file size. An actual readable screenshot has its advantages...

#177So windows 11 easily bypasses this when taking a screenshot. Just switch to video mode. (Yeah yeah. Not technically a screenshot but same default software built in to windows.)

#178Earlier quoted context omitted.
Neat idea. A friend of mine made a similar animated GIF type captcha a few years ago but based on multiple scrolling horizontal bars that would each reveal their portion of the underlying image including letters, and made a (friendly) bet that it should be pretty hard to solve. Grabbing the entire set of frames and greyscaling them, doing an average over all of them and then applying a few minor fixups like threshold…
That's reminiscent of a (possibly apocryphal?) method I once read about to get "clean" images of normally crowded public places - take multiple photos over time, then median each pixel. Never had the opportunity to try it myself, but I thought it sounded plausible as a way to get rid of transient "noise" from an otherwise static image.
That's a real method:

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.

Good one. Just found the game I was trying to find for the initial comment: "No Signal" (https://www.tiktok.com/@teekenng/video/7520954215116639496)
Really clever use of a TV remote as controller.
