PSA: Viewing strobing images has caused temporary (lasting hours) backlight issues on my 2021 Macbook Pro, in the past. Somehow, it causes the backlight to continue flickering for some time afterwards, even when looking at static images. It is barely perceptible, but quite noticeable at the edges of the screen - enough to be annoying. I have no idea if this is a hardware issue with my specific unit, or a more widespr…

Are you sure it's your backlight and not your eyes? (Something like this: https://en.wikipedia.org/wiki/Motion_aftereffect)

EPILEPSY WARNING. Extreme strobe upon opening OP link. while (true) { websocket.send(JSON.stringify({ action: 'plus' })); } Really messed with my vision and crashed chrome. Fun experiment!

no crash with:

setInterval(() => { websocket.send(JSON.stringify({ action: 'plus' })); }, 0)

Strobe warning in case someone might be susceptible to it. You got a chuckle out of me.

Hypothetically if someone suffers a seizure... who is responsible? The platform provider or users who switched the light on and off?

those who made the web stadards capable of doing _anything_ with the user's computing environment, let it be any useless/arbitrary, and those who forced this arbitrary code execution platform to be the same as the information browsing / catalogue system / document viewer platform what the web originally meant to be.

today users can not manage their bank account, enlist to classes, read newspapers online without the real fear of mining bitcoin for someone involuntarely, DDoS-ing goverment sites by hidden pixels, presenting unsolicited unrelated content to his audience on a presentation, and now, having sight damage...

Still broken. I think it's because it's overloaded and the websocket fails to connect, I'm getting a 504 Gateway Time-out.

There is a company that is selling a LED Lamp that blinks at 40 Hz. They claim it can mitigate Alzheimer's.

This line of devices has become known as 'Gamma Flashers', lots of knockoffs today. From Gamma brain wave state.

There is some, small amount, of science to back this up.

So who is going to be the first person to put up a 40 Hz flashing website? With appropriate warnings about Photosensitive Epilepsy before showing the page.
