This idea has made me think of another subject - would it be possible to overload a face / car plate scanning camera by using a pattern, like qr code for exampl? Or a jacket made of qr codes?

This makes me feel motion-sick, which is kind of impressive because I'm normally not easily susceptible to that.

My eyes went straight into seeing 3D image mode. It's the easiest one I've seen yet! /s

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?
