everything old is new again, and toys will be toys

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).
While this is interesting, what I really wanted to see was more 'graffiti' and less 'laser'.
Graffiti, fundamentally, is a defacement of public property as a form of artistic self expression. To that end, why not combine this with a laser engraver instead of a laser pointer?
Imagine hooking this up and then literally carving your graffiti into the side of a brick building. Or burning it into the paint on a metal container car.
Obviously such a thing has the potential for serious bodily harm and could start building or wild fires inadvertently, to say nothing of the energy consumption requirements such a laser engraver would necessitate.
Counterpoint: rule of cool.

These green laser pointers are bright enough to cause eye damage from the reflection off surfaces, for humans and pets.

Not drawing (yet), about to arrive, but I built a whole projected arcade system on the same vibe, but way before vibecoding… :)
This is really cool! I wonder if for the drip on neon you could make it start from the bottom of the line to make it a little smoother. And maybe you could try making it translucent for the marker so it matches the marker ink.

So cool! I can see its application in presentation. Does this support more than 1 laser btw?

very cool, I can imagine use-cases like a friends evening playing at home with the projector or even school doing didactic.
