Ha cool! How’s it work?

Lalabadie2• 10 months ago

The only way to see the text is in the movement. The pattern across any single frame is entirely random noise.

thaumasiotes2• 10 months ago

The pattern across any single frame is entirely random noise.

This is untrue in at least one sense. The patterning within the animated letters cycles. It is generated either by evaluating a periodic function or by reading from a file using a periodic offset.

tgv• 10 months ago

It's not a great visual, but like this: https://michaelbach.de/ot/cog-Dalmatian/

cryptoz• 10 months ago

Had a lot of fun trying to break this. Turns out you can screenshot real easily by zooming out. Maybe there are other ways but I stopped trying :)

sans_souse• 10 months ago

Not sure what you mean - I can screenshot it freely that's not the point the point is if you look then at the screenshot you cant discern the text because its a single frame now

dwg• 10 months ago

Zooming out before taking screenshot and the text is no longer obfuscated. I tried and confirmed it works. In fact, the text is perhaps even more readable than the original.

esafak• 10 months ago

He's right. This is zoomed out: https://imgur.com/a/G7CKZ94

This is on MacOS 15.6, Chromium (BrowserOS), captured with the OS' native screenshot utility. Since I was asked about the zoom factor, I now tried simply capturing it at 100% and it was still perfectly readable...

I guess the trick doesn't work on this browser.

vunderba3• 10 months ago

yeah - I actually was initially confused since I wasn't having any issues screenshotting it but had forgotten that I have the default site zoom set to ~65%.

altcognito• 10 months ago

Fun side effect: staring at the letters for a bit makes the rest of the image move.

Izkata2• 10 months ago

Firefox on Android seems to just be a static image, I can't see any text.

stevage• 10 months ago

Wfm

creatonez2• 10 months ago

Probably the result of canvas fingerprinting protection configured in your `about:config`? With a default profile it seems to work fine on Firefox for Android.

Izkata2• 10 months ago

I haven't changed any of that on here.

Looks like I consistently get just the static image when I open in a new tab then switch to it, but then if I refresh the page without switching tabs it'll show the animation.

kemayo• 10 months ago

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

dylan6047• 10 months ago

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

RedShift1• 10 months ago

Heh my eyes felt like they started bleeding

hnlmorg• 10 months ago

Hello fellow person from the 90s. mine eyes did the same too.

dylan6047• 10 months ago

Has anyone tried a long exposure to see if the motion smears into something discernible? Obviously harder to expose a bright screen without some ND since the shutter speed is the phone's main exposure control

dasil003• 10 months ago

How do you take a “long exposure” screenshot? Isn’t every screenshot a perfect digital copy of a single frame or a full on video?

dylan6047• 10 months ago

Clearly, I meant using a camera, and I'm guessing you knew that too

sprobertson• 10 months ago

Here's the screen recording version of a long exposure (thanks for the nerd snipe) - https://gist.github.com/spro/7599415b0e47de65311557b3454771a...

shawnz• 10 months ago

Perhaps this technique could be defeated by scrolling the background in the opposite direction as the text

dylan6047• 10 months ago

That's what I was expecting to see. I didn't have a mount for my phone handy, to try it. The exporting of frames from a video is a good compromise though. nice one

lodovic• 10 months ago

If you zoom out to 25 % the text is clearly visible and screenshottable.

EvgeniyZh• 10 months ago

Probably the lower frequencies of noise are not matched? Not sure if the frequencies of the order of movement frequency can actually be matched

alliancedamages• 10 months ago

You can also break it by recording the screen, of course.

xnx3• 10 months ago

This game disappears if you pause it: https://youtube.com/watch?v=Bg3RAI8uyVw

vunderba3• 10 months ago

This is great - seems to be the same effect of hiding a shape using an animated noise pattern on a background of static noise.

They even provide the source code for the effect:

https://github.com/brantagames/noise-shader

nomilk• 10 months ago

First time seeing this, makes me smile involuntarily.

sunrunner2• 10 months ago

This is great. The sphere example looks especially pleasing. It also reminds me of the game The Voidness.

robertlagrant• 10 months ago

Yes - I was thinking of this. It solves various complicated problems such as rendering distance information in this format.

krzat• 10 months ago

Interesting that the perception of objects/text does not disappear immediately, there is smooth fade out.

lproven• 10 months ago

Not really a game, but neat all the same.

It reminds me of the mid-1990s video game Magic Carpet.

https://en.wikipedia.org/wiki/Magic_Carpet_(video_game)

This was a pseudo-3D game and on an ordinary display it used perspective to simulate 3D like most games. If you had 3D goggles it could use them, but I didn't.

However, it could do a true 3D display on a 2D monitor using a random-dot stereogram.

https://en.wikipedia.org/wiki/Random_dot_stereogram

If you have depth perception and are able to see RDS autostereograms, then Magic Carpet did an animated one. It was a wholly remarkable affect, but for me anyway, it was really hard to watch. It felt like it was trying to rotate my eyeballs in their sockets. Very impressive, but essentially unplayable and I could only watch for a minute or two before I couldn't stand the discomfort any more.

xnx3• 10 months ago

I played the game, but had no idea about that feature.

Also playable in the browser: https://playclassic.games/games/action-dos-games-online/play...

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.

markasoftware• 10 months ago

same thing, but a game: https://brantagames.itch.io/motus

zikero• 10 months ago

Another 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 outline.

- I tried also having the text itself move (bounce like the DVD logo). Somehow makes it even more readable.

I definitely know nothing about how LLMs interpret video, or optics, so please let me know if this is dumb.

squigz• 10 months ago

As if captchas aren't painful enough for visually impaired users...

xandrius• 10 months ago

I don't think we need more capable people thinking of silly captchas.

ATechGuy• 10 months ago

Why? stopping LLM crawlers is a need now. We've seen more capable people working for undergrad dropouts.

pwdisswordfishz• 10 months ago

Take N screenshots, XOR them pairwise, OR the results, then perform normal OCR.

ranger_danger4• 10 months ago

Yes but this is prohibitively expensive for a large bot network to employ.

Wasn't that the whole point of Anubis?

UltraSane• 10 months ago

Seems trivial to diff multiple screenshots to identify what parts move. Or just use a compression algorithm to do the same.

dazzlevolta• 10 months ago

Would 2 screenshots be enough, I wonder?

boothby• 10 months ago

Yeah, the letters are big enough, an xor shows the text quite clearly.

kps• 10 months ago

The text reappears when I screenshot it twice.

Syntonicles• 10 months ago

I first saw this effect in a video from Branta Games.

https://www.youtube.com/watch?v=Bg3RAI8uyVw

The effect is disrupted by introducing rendering artifacts, by watching the video in 144p or in this case by zooming out.

I'd love to know the name of this effect, so I can read more about the fMRI studies that make use of it.

What I've found so far:

Random Dot Kinematogram

Perceptual Organization from Motion (video of Flounder camouflage)

https://www.youtube.com/watch?v=2VO10eDIyiE

shannifin2• 10 months ago

Others have mentioned Branta Games, but I first saw the effect here: https://youtu.be/TdTMeNXCnTs

zem• 10 months ago

thanks, that's also the best explained one!

cubefox2• 10 months ago

This one is actually more sophisticated because it doesn't rely on scrolling pixels like the OP. So the object doesn't just disappear in screenshots, but also when the animation stops moving! So you can't actually display text that stands still, like the "hello" in the OP.

optionalsquid• 10 months ago

I'm not sure I follow. Couldn't you display text that stands still by (re)drawing the outline of the text repeatedly? It would essentially be a two frame animation

shannifin2• 10 months ago

Yep. He tries text in another video by flipping pixels for one or more frames, so the words disappear very quickly. Definitely harder to read, especially longer words: https://youtu.be/EDQeArrqRZ4

alanfalcon• 10 months ago

Not technically a screenshot, I guess, but trivially easy to do with software I had lying around all the same. https://media4.giphy.com/media/v1.Y2lkPTc5MGI3NjExYXloZ3Z0NT...

CaptainOfCoit• 10 months ago

On Android: Take a look at the URL, see the text in plain-text :)

catlifeonmars5• 10 months ago

Nice. I did not think to look there.

HarHarVeryFunny• 10 months ago

A single photo is good enough as long as the exposure time is long enough to capture the motion blur.

catlifeonmars5• 10 months ago

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.

hbbio• 10 months ago

Coinbase was hacked for $400M when literally someone from outsourced support services was taking screenshots on their phone!

The culprit had more than 10k photos of all security details for thousands of wealthy customers.

gloosx• 10 months ago

If it's even true someone from outsourced support has access to some sensitive security details then using this dumpster is almost like throwing your money out of the window.

axiolite3• 10 months ago

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.

cloudbonsai• 10 months ago

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)

azinman2• 10 months ago

You could also just record a video.

axiolite3• 10 months ago

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...

chinathrow• 10 months ago

use CTRL-Tab

Thank you forever for this, I ever used Ctrl-Page up/down for that.

Velocifyer• 10 months ago

Or use Blink Comparison from F-Droid.

sunrunner2• 10 months ago

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 thresholding and contrast adjustment worked easily enough as the letters were reveleaed in more frames than not (I don't think that would affect the difficulty much though if it were any diffierent). After that the rest of the image was pretty amenable to character recognition.

aw16211072• 10 months ago

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.

amelius2• 10 months ago

Yeah if this became popular, we'd have another Show HN for a tool that automated that.

postalcoder• 10 months ago

Out of sheer curiosity, I put three screenshots of the noise into Claude Opus 4.1, Gemini 2.5 Pro, and GPT 5, all with thinking enabled with the prompt “what does the screen say?”.

Opus 4.1 flagged the message due to prompt injection risk, Gemini made a bad guess, and GPT 5 got it by using the code interpreter.

I thought it was amusing. Claude’s (non) response got me thinking - first, it was very on brand, second, that the content filter was right - pasting images of seemingly random noise into a sensitive environment is a terrible idea.

burstmode• 10 months ago

pasting images of seemingly random noise into a sensitive environment is a terrible idea.

Only if your rendering libraries are crap.

bonyt• 10 months ago

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

loopduplicate• 10 months ago

Bottom layer normal, second layer grain extract, top layer vivid light. This completely blacks out the whole area outside of the text.

viccis3• 10 months ago

For what it's worth, there are some websites that embed some crazy shit when you screenshot. On reddit, r/CenturyClub will fill your background with a slightly off-white version of your username so that they can identify leakers, and I'm not certain how exactly they do it.

dgan• 10 months ago

buibuibui• 10 months ago

This could be used for Captcha systems. Would current bots be able to decipher these?

ranger_danger4• 10 months ago

Yes, you can make ChatGPT decipher this already.

But doing this on a massive scale would warm the planet.

And it's not friendly accessibility-wise.

giamma• 10 months ago

It's a nice effect, but I don't think it's usable in practice, because it's not accessible for visually impaired users: not enough contrast between foreground text and background

amelius2• 10 months ago

Yeah but the randomness may produce all kinds of NSFW stuff ...

Also, it's even harder to read than most captchas.

But fun idea, it was nice to see.

oniony• 10 months ago

I don't see any text: just a scrolling down screen of random black/white pixels.

rnhmjoj• 10 months ago

It seems to depend on reading pixels from a canvas. This is commonly used for fingerprinting users on the web, so you have to disable some privacy plugins.

Aeolun• 10 months ago

This should have an epilepsy warning. Or something of that kind. It certainly made me feel sick.

dorianmonnier• 10 months ago

injidup• 10 months ago

This is more a curious question for those affected by epilepsy. If you know you are triggered by such things how long an exposure is required to trigger an effect. Are you able notice that media may be triggering and simply close it or is exposure and triggering almost instantaneous?

a3w• 10 months ago

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.

tamimio• 10 months ago

In your phone, just record the screen, then drag the player to see how every still pic blend in within the surroundings, but as soon as it moves it shows up.

pmontra• 10 months ago

If anybody implements that to antiscrenshot some sensitive data, somebody else will use another phone, a tablet or a camera to record a video of it. Nice idea though.

jonathaneunice• 10 months ago

Or the same one.

While a screencap image hides the message, a screencap video shows it perfectly well.

Could 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).

grumbel• 10 months ago

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.

andai• 10 months ago

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.

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.

jiehong• 10 months ago

I have to admit it's a pretty cool idea.

At first I was worried that there was a (stupid) API in web browsers just like on mobiles to prevent users from screenshotting something by blanking the screen in the screenshot.

I feel like there’s an ethical issue. If something is on my screen I own it. I know the law doesn’t agree but it feels right to me.

sarreph• 10 months ago

The point is that it's noise and you can't "capture" a still image of the text / information (relies on motion to be viewable).

ranger_danger4• 10 months ago

We figured out how to capture video though. And ChatGPT can already decipher this.

NKosmatos• 10 months ago

Nice one, the good (great?) thing is that you can save this as a plain old html and you've got the whole code :-) It hasn't got any type of license included or any other info as comments, so perhaps the creator or the OP can let us know.

This would make for a great effect for a technothriller. Like a cyber ransom or something like that.

landgenoot3• 10 months ago

I think there are usecases for this.

Some countries switched to identity apps instead of plastic identity cards. You could make sensitive data non-screenshottable and non-photographable.

A modern variant to the passport anti identity fraud cover: https://merk.anwb.nl/transform/a9b4e52a-9ba1-414b-b199-29085...

The hotel you are checking in doesn't need to know your DOB, length, SSN, birth place, validity and document number. But they will demand a photo of the ID anyway.

jlokier• 10 months ago

You could make sensitive data non-screenshottable and non-photographable.

That made me curious, so I took a photo of my laptop screen running this page.

With default camera settingse, the text wasn't visible to me in the photo on my phone screen.

However, setting the exposure time manually to 0.5s, the text came out white on a noisy background and I could easily read it on the phone screen.

I would not be surprised if the default camera settings photo could be processed ("enhance!") to make the text visible, but I didn't try.

landgenoot3• 10 months ago

I think it also depends on the response time of the display and even the temperature.

jerf• 10 months ago

On my Chrome-descended browser, the initial screen is populated by something that appears to be some sort of downsampled grid image, resulting in black and white, but also various shades of grey. However the scrolling text is pure black and white. It also seems the canvas is persistent, so the result is that text on the canvas is leaving a shadow for me, where I can still read the shadow. Somehow the initial noise is not coming out as just black and white pixels.

landgenoot3• 10 months ago

I'm wondering. Can we also come up with something the other way around? Text you cannot read, unless you take a screenshot?

adrianmonk• 10 months ago

You could probably do it with timing tricks related to video refresh. Wait until the monitor has finished refreshing, then draw the text into the framebuffer. Leave the text there a short while, but erase it before the monitor starts refreshing again. Repeat.

The screenshot would have a chance of capturing the text, depending on exactly when the screenshot pulls pixel data out of the framebuffer.

This might not work on certain devices. You need access to the refreshing timing information. The capture mechanism used for screenshots might also vary.

rompic• 10 months ago

Maybe not exactly what you meant but it reminded me about the following: When one of our apple servers failed a decade ago and just vomitted out walls of error logs too fast to read anything,the apple support guy we called took his smartphone and made some photos to read and fix the error.

gnramires• 10 months ago

If you have a very high enough refresh rate display, then yes: just flash alternatingly black-over-white and white-over-black text (i.e. invert it). We perceive essentially a low-pass filtered visual input (with limitations like neural firing rate), eventually it should appear as just uniform gray. Maybe adding some confusing elements might make it feasible at lower refresh rates.

Theodores• 10 months ago

let textString = `hello`

I think further obfuscation could be possible by uglifying the script and providing a SVG path that stores the text as some vector image.

Self modifying code could be useful too, to delete the SVG data once it is in the canvas.

I fully expect this to still be defeated by AI though, such is my presumption that AI is smarter than me, always. It won't care about uglification and it would just laugh to itself at my humble efforts to defeat Skynet.

Regarding practical applications, nowadays kids sell weed online quite brazenly on platforms such as Instagram. Prostitutes also sell their services on Telegram. It is only a matter of time before this type of usage gets clamped down on, so there may come a time when this approach will be needed to thwart the authorities.
