Its about using the road as a canvas

Spectators have always chalked messages of support along the Tour de France route - how about using the web to bring the roads of Franceto everyone and spread messages of hope in the fight against cancer?

A unique project to support Nike's Livestrong campaign which saw messages of hope in the fight against cancer chalked along the Tour de France route was done by Wieden+Kennedy Portland and development partners DeepLocal and Standard Robot, Nike created a giant robotic writing tool.

Over the course of the 15-day event Chalkbot (chalk writing machine) picked up more than 4,000 followers on Twitter and received more than 36,000 texts and twitter messages!
