A very simple, yet effective idea to paint the streets: Just put some kilos pigment on a very frequented crossing and the bikes and cars will do the painting. As seen yesterday at Rosenthaler Platz, Berlin, a yet to be named group of streetartists used the popular place in Berlin Mitte to install their spontaneous piece of art.

Here are some impressions via Flickr:

Not surprisingly, the story soon got twittered and blogged and some newspapers caught up the news as well:

“Minutes before, bikers had poured paint from big boxes in front of cars that waited for green lights. So the cars and their wheels, if the driver wanted it or not, became the brush tool for this guerilla public art piece.”

I caught the fotos from Just Blogsport you can watch a video on Kraftfuttermischwerk, even De Telegraaf from the Netherlands had it as news, and Berlins daily newspaper BZ states:
“Die Autos verteilten die Farbe auf der Fahrbahn, bis eine überdimensionale Trikolore aus bunten Streifen enstand.”

It is unclear who is behind this project, I have a guess and will research a bit more.
