PIC controlled spray paint

Most people make LEDs light up for their first microcontroller project. [Alex] built a “large scale dot matrix printer.” This beast is a PIC controlled ground graffiti machine. As it rolls across the ground it deposits strategically located bits of spray paint. Rather than use actual spray paint, he opted for a set of solenoid controlled nozzles that shoot the paint downward.
this looks like it could be the basis of an interesting business. “give us your images and we’ll paint them wherever you want them” and rig it up to go up and down a wall, on someone’s driveway, etc.
