Fantastic idea. I wish I would have know about this during the tour. A very good friend of mine who is an avid cyclist has recently gone through his fourth brain surgery to remove cancer. He no longer can ride due to loss of his peripheral vision and increased seizures, but after his third surgery he could still drop me on every climb.
This was a great campaign by Nike and LIVESTRONG on the Tour de France this year. You were able to tweet inspirational messages to @chalkbot and selected messages would get painted in chalk on the tour route ahead of the racers.
