everything old is new again, and toys will be toys
This is even older (I think), similar idea of building interactive experiences using off-the-shelf lasers: https://web.archive.org/web/20040202205307/http://www.monzy....
Heh I was just about to say, people were doing stuff like this at Parsons/ITP a decade and a half ago, at least...haven't thought about GRL in a while, thanks for the flashback
This is what I immediately thought of as well, I'm just grateful you remembered the name of the project.
An absolute blast from the past, thank you for unlocking the memories of me reading these cool projects way back when!
Very cool. I remember seeing a video of some people doing this on a whole building… found it: https://m.youtube.com/watch?v=DKbtTPYZEig&t=30s
same crew as is referenced here too: https://news.ycombinator.com/item?id=49513717
Not drawing (yet), about to arrive, but I built a whole projected arcade system on the same vibe, but way before vibecoding… :)
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.
Defacement is not the point of graffiti. It's fundamentally visual, not fundamentally destructive.
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?
Looks cool!
very cool, I can imagine use-cases like a friends evening playing at home with the projector or even school doing didactic.
love the whole simplicity and the style too.
Consti, this could do well on IG and TikTok.
Love the take on AI
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.
