What a clever idea! My very first thought was "bullshit!" when I saw the title on HN but after my actual brain had a real chance to think about it I immediately reversed course.
It's cool to think that an interpreted language running in a browser can actually fix hardware, for a certain definition of fix.
Sometimes you can clear a stuck pixel with a gentle massage - just don't use too much force. Doesn't work if there's a sheet of glass in front of the screen, of course.
Usually when I get a new screen, the first thing I'll do is check it out with a pure screen of each of red, blue, and green, which tends to show up stuck subpixels.
having used these type of programs for years, I like that your allows targeting a specific screen area rather than full-screen snow. Keeps the headaches down. Thanks.
Has anyone actually repaired their screen with it? For me, it just didn't work; after four hours or so, I simply gave up.
(Sony LCD screen, really high-quality, a few stuck pixels in a specific area)
I left it on overnight once. It worked. The pixel re-stuck several times after so it took a few more sessions. It's been normal going on a few years. You might try rubbing the pixel area a bit and testing other stuck pixel fixing software.
I'd like to see some evidence for that ">60% success rate". Programs that do this have been around for a long time (e.g. http://udpix.free.fr/index.php?p=about ), and having talked to some people who have tried them in their repair shops on customer's monitors overnight, it's more likely that pixels which were stuck in the first place are either truly stuck, or intermittent ones that come and go due to minor fluctuations in pressure and heat, and that those claiming to have theirs "fixed" by this program might just be because they left their monitor on long enough that the small temperature increase induced by the cycling was enough to close an intermittent connection.
Those that can truly be fixed with slight pressure/"massaging" can also be similar - intermittent electrical faults - or foreign matter/voids in the liquid crystal itself.
They took great care to make sure the ads were unobstructed.
My observation of the noise box is that it doesn't appear to be tuned for retina screens and it seems to be a 5x5 box where each cell has the tame square texture.
Gave me a head ache staring at it for about two minutes though.

Definitely. My comment was not a sarcastic "they just want ad views", it was a genuine compliment. Good for fixing a screen as well as getting "extended" ad views.
If the pixels are being interpolated they'll be less likely to be completely white or completely black. I'm not sure how much that matters, but if you're going to leave this site on for a while it seems like you might as well go to the effort of turning off pixel scaling.
I had a stuck pixel on this very Nexus 7. It stayed red for a few days as I played some 24hr YouTube vids that used the exact same principle. After ~2 days, no wonky pixel. Honestly, I think it was temp fluctuation, but whatever... it is fixed. :)
I have no stuck pixels currently and I try to forget the whole experience as I might have almost junked the N7 because of my annonying Jr-OCD.

I got few pixels unstuck by using similar apps and massaging the screen, but recently I got one black pixel which doesn't react to anything.

And if it works, cool. I never had a dead pixel as far as I remember.
