Graffiti-Proof?

When you travel around by subway in Germany....you often sit there and gaze at the various graffiti that punks draw on the seats.  It usually doesn't matter where you go....it's done.

Well....I did a Berlin trip in the last day or two, and came to sit on a subway seat...with a unique design.  I'm of the opinion that the design is such.....making it almost impossible to draw or paint some saying on it.

I sat there for at least a minute looking at it.  You just don't see this design anywhere much, and it dawned on me....it's graffiti-proof.  Well, maybe.

I admit, it does look awful bad.  But I think the intent is to stall the punks and make their life's work more difficult.
