Neat! I've seen stuff like this that works as a magic eye thing. So you cross your eyes (or make them parallel, depending on the type of image) and it makes a 3d animation appear in front of the page.

#93This should have an epilepsy warning. Or something of that kind. It certainly made me feel sick.
I saw the game using this rendering weeks ago, looked okay. Now I saw a font and tried to hold on to the edges while reading it, and yes, somehow this made me more (sea) sick. Strange.
Perhaps faces would be strongest in terms of reaction.

#94Could someone please post what this disappeared bit is supposed to look like? Looks legible to me when I screenshot and open in Preview on MacOS 15.6.1 (Firefox).
You are probably browsing with zoom, that seems to screw up the up rendering and makes the background and text look different. It should be just black&white random pixel noise for both background and foreground, without motion the text becomes invisible, as it blends with the background.

#95This 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?

And another version of this, using apples instead of white noise

#97You 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?

#98Another idea I had with this concept is to make an LLM-proof captcha. Maybe humans can detect the characters in the 'motion' itself, which could be unique to us? - The captcha would be generated like this on a headless browser, and recorded as a video, which is then served to the user. - We can make the background also move in random directions, to prevent just detecting which pixels are changing and drawing an outli…
Take N screenshots, XOR them pairwise, OR the results, then perform normal OCR.

Re: Show HN: The text disappears when you screenshot it
#100Fun!
I always wanted to make text that couldn't be recorded with a video recorder, but that doesn't seem possible.
Maybe if you knew the exact framerate that the camera was recording at, you could do the same trick, but I don't think cameras are that consistent.
