Space invaders pixel sound

Unfortunately in a bad quality, but somebody filmed (for the first time on youtube in germany i guess) graffiti on freight trains passing by. I hope that more will follow in a better quality, it's quite interesting if there is at least at every wagon a panel.
There are a lot of youtube-train-nerds who film the trains, but no one focuses on graffiti as well as this guy did.

Back to the video: you see panels by Ridim, Pusher, Enemy, Oslo

The 2nd video features: Buda, Frei, Pusher, DBF
