Hi HN and สวัสดีครับ! I remember seeing this the first time in Vienna by a friend of mine, Michi who came back from NYC and I believe he learned about it at the local hacker space at the time: NYC resistor.

I knew Michi through the Metalab, our hacker space in Vienna. Originally the idea seems to have been from the Graffiti Research Lab, which is also what I've linked to on my page and in the repo's Readme.

I think the version that Michi used was a MacOS app (not sure which framework), but I've always wanted to make it a web app. So all you need now is a projector, a laser pointer, and a laptop (with a camera).

I've already tried a few fun setups (eg using the iPhone's camera or using AirPlay connected to the projector). It's quite flexible.

Let me know if you end up using it and please share videos / photos and I'd be happy to put them up.

I know the original is old-skool cool, which I think makes this a fun project.

I'll try to set it up at the next CCC (2027) - if you see me there, come say Hi (I'll probably be in a banana costume).

Thanks! This was absolutely the inspiration - and I've also mentioned it on the page (right under the video) and in the repository's Readme.

I haven't tried, but it should be possible to do so pretty easily.

Thanks! I'm not much of a social media person (went so far that I made an Apple shortcut app to launch IG in the messages screen[0], so I can avoid the feed). But maybe I'll try to post something there.

Great writing - and happy for you that you seem to have made some friends!

I did

Just checked and it also installed itself on my phone. iPhone 17 Pro, non-US App Store, on latest iOS beta, no MDM. Sounds like an Apple Store bug to me.
