Damn this looks like fun. I have no idea how it works, well, lasers yes. Beyond that it looks like you need an old RV filled with magical things. Whatever it is, it allows you to write graffiti on the sides of buildings with a laser pointer like gizmo. Clearly these guys aren’t really qualified to use such a cool gadget. I watched the whole video and not once did they graffiti a pair of boobs on the building. Come on, you know you would have done that.
