Guerilla artists give intersection a colorful new look

Take a busy intersection, like Rosenthaler Platz in Berlin. Let a group of guerrilla artists pour 500 liters of water-based, environmentally friendly paint onto the pavement.

Then add 2,000 cars, bikes, and buses. And what you get is this: A really cool video of street art or, at least, lines of red, yellow, blue, and purple paint that blend and merge in real time. Who knew driving could be so artistic?

The public art project, titled "Painting Reality," was the brainchild of a group of artists called IEPE and the anonymous crew.

The video shows bicyclists dumping trays of paint at each intersection. At first the paint pools on the street, until the traffic drives through it, pushing the paint across the street. The lines of color intersect, bleeding into one another and varying in thickness.
