Remember chalking up the road and driveway as a kid? Well imagine how exciting a huge robotic chalk ink jet printer would be. And it can write whatever you want! The guys and gals at Nike are taking interactive guerrilla marketing to the next level with the Chalkbot. The celebrity that is Chalkbot was the first on the streets at the Tour de France this year. Anyone can send an inspirational chalk message to riders regarding a personal cancer story. You can even text message the Chalkbot by sending “LIVESTRONG” and your message to 36453. What better canvas than the open road? We say way to take it to the streets, and what a great cause.
