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

#33Reminds me of messing with old laser pointers as a kid, but way more sophisticated. Love seeing creative uses of tech.

#34Immediately thought of WarGames. The applications for temporary outdoor displays are super interesting.

#35Always wanted to mess around with a projector like this! The alignment problem on weird surfaces must have been a fun challenge.
Re: Show HN: Laser Graffiti
#36Always wanted to build something like this! Brings back memories of trying to control cheap laser pointers with an Arduino.
Re: Show HN: Laser Graffiti
#37While 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 con…
> Graffiti, fundamentally, is a defacement of public property
Both wrong. Neither is defacement the point nor doing it to public property. Fundamentally it's a visual art form and whether that's on private or public property is insubstantial.
It's surely intervoven with anarchic protest and that's where the defacement angle comes in. Similarly, public property as a symbol of the state that is rejected plays often a role. Though that's ironic too since if the "artist" comes from a left-leaning anarchic background then damaging public goods is kinda counterproductive, as opposed to private property of the rich who are the more usual target for symbolizing oppression of the poor.

#38triggered some memories of other fun projects:
- gray scale image made from laser and fading glow in the dark paint https://www.youtube.com/watch?v=FUa9UgAZTIY
- i remember a version of this phosphorescent wall at the los angeles children's musuem. a strobe imprinted your shadow. https://www.exploratorium.edu/exhibits/shadow-box

Both statements are wrong. But yours is wrong-er. You are thinking of street art. Or just spray paint art. The whole point of graffiti is to "get up". If you don't know what getting up is, you should not be espousing any opinions on what graffiti is and isn't.

I was hoping for the same. If we're going to live in a cyberpunk dystopia we could at least have some cool anarchist tools to go with it.
