Do you remember the GraffitiWriter Remote Controlled Truck? Now the same concept has been applied to a bike with a purpose.
Meet the latest techy, wise and environmentally conscious protest ever. Design and computer geek Joshua paints the streets of New York just before the Republican Convention with a bicycle that prints chalk based paint in a dot matrix manner. The bicycle is online and actually you can send messages to Joshua so that his bicycle can print on the go. There are also videos at the Wired page. Don't miss this. This is Protest 2.0
