It's sort of impressive that they could have that many devices in sync but the actual light show they chose was extremely meh. Just lots of flickering, which even when synchronized, isn't visually impressive.

>>109140312
was that a hack? or just a webpage with some javascript?

>>109140312
>linked up
Nothing was linked up. It just flashed the light to a sequence based on a fucking timer.
Kill yourself.

Is there a way to safely scan QR codes? Or some website that can open them sandboxed (especially on PC)?

>>109141794
no, QR codes always instantly steal your soul

>>109140312
Is there a version of this without the shitty 4chan compression requirements making it look so blurry

>>109141823
Well, you are holding a phone while scanning them so that was already long stolen.

>>109140312
Fake news.

>>109140381
This, op is a faggot

>>109140332
just scanning the QR code doesn't give them a location, so I don't see how they could make an actual light show when they don't know where a phone is located.

>>109142196
although synced to a good song it would probably be badass

>>109140312
how brown do you have to be to find this impressive

>>109142196
if you watch the video, then you will notice the 'show' is random flashing then synced flashing
no spatial information required for that much

>>109142196
what they could do instead is stick an individual QR code to each seat. then they could do a complex light show.
or if there's some kind of stadium ticket app integrate it into that.

>>109142196
If the QR code linked to an actual app, that could make use of GPS. There's some error involved and the crowd is dense, so they couldn't do something like make each person a pixel, but they could get some lower level of resolution. Certainly enough to do waves and simple animated shapes.

>>109142196
Just have different qr codes in each block or even smaller units
