This is So Kanno and Takahiro Yamaguchi's "Senseless Drawing Robot," a vandalism machine that uses programming and its own momentum of spray the heck out of clean walls.

If the machines ever take over, they'll be so compelled to emulate their extinct makers that a Senseless fleet will roam the microchip cobblestones, spraying paint over all of the cog shops and plug emporiums (with its comrade-in-arms Robo-Rainbow). This bot was on display in Tokyo last month.
