Nike | Chalkbot

Chalking the roads is a Tour de France tradition. Spectators write messages of encouragement to their favorite riders. The Nike Chalkbot was a way to take this positive message even further. It brought the roads of France to everyone. By sending a message to the Chalkbot through SMS, web banners, Twitter or WearYellow.com, people around the world were able to make their mark in yellow. Over the course of a month, the Chalkbot gained over 4,000 followers on Twitter, received over 36,000 messages and printed thousands of them over 13 stages of the Tour de France. By Weiden+Kennedy.
