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.
> 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.

You’ll probably burn your retinas with the backscatter
Defacement is not the point of graffiti. It's fundamentally visual, not fundamentally destructive.
Ask the people who have to clean it off.
