Consti, this could do well on IG and TikTok.

Love the take on AI

con•2d ago
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.

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.

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.
doanthu249•1d ago
So cool! I can see its application in presentation. Does this support more than 1 laser btw?
con•1d ago
I haven't tried, but it should be possible to do so pretty easily.

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

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.
