Chalkbot

Here's a great short video (2 minutes) about the Chalkbot robot that Nathan Martin and David Evans from deeplocal built by hand. The Chalkbot was funded by Nike writes messages with, you guessed it, chalk, on concrete and was featured in this year's Tour de France. It's awesome! Now if only these were affordable I would totally get one and run it all the way up and down Carson and Penn printing images!
