This is a simple and effective filmic story that’s about a complicated concept that some engineers translated into a powerful and effective idea.  We should see a lot of this in the future.  It’s a robotic painting machine called Chalklbot funded by Nike and Livestrong.  People submit messages which are reviewed – from the pool 100,000 will be chosen to get printed along the Tour de France route.  Cool idea.  This is not only a great idea but it’s also well crafted film explaining the cool idea.
