April makers challenge #3/30: graffitibot

What: a robot that runs around and poops out a tag (or when I get smart enough, customizeable "CNC" graffiti. Everything will be legal (of course)

Objectives: go about and spray tags on floors / walls / ceilings

How: was thinking of a simple servobot first, then with rangefinding via market cones or something. Simple version would be valve control on a spraycan with a stencil close to the ground. Complex would be a single CNC

Application: who cares why? Could also be used to work on industrial "branding". Yeh.
