Lance Armstrong and Nike's Livestrong partnered with DeepLocal and StandardRobot to develop this Chalkbot, designed to spray 100,000 messages of courage, hope and action along the 2009 Tour de France for people that've been affected by cancer.

If you've ever seen the Mythbusters episode where Adam and Jamie build an 1100 barrel pneumatic paintball gun to paint the Mona Lisa instantaneously, then you know what these amazing systems are capable of. Check out the video to see how they built and tuned the truck-pulled Chalkbot pneumatic chalk spray gun


The Chalkbot made its official debut Sunday during the 2nd stage of the Tour de France. (Hat Tip To Julia!)
