Is it legal to shine a computer projector onto the side of a building?
I got a cool app for my back that uses a webcam to see where ever I am pointing with my green laser pointer, and then using the projector it leaves a trail where ever I shine the laser.
so basicly If I was to draw something on the building or write a name with my laserpointer, the projector would continue to show it until I cleared it or turned it off.
What are the legality’s of doing this here in the USA?
