artistic traffic…

“a “group of cyclists” in berlin dumped many gallons of paint into the middle of rosenthalerplatz, letting pedestrians, cars, and bikes create a colorful collective work of art. and not to worry environmentalists, the creators of the project posted signs on post nearby explaining that the paint wasn’t harmful and would simply wash off with water.”
