That's it, I have assisted to my first freeze party today.
I knew theses type of events, because there are a lot of groups about this subject on internet. The aim isn't really complicated: just stop moving during five minutes to show how the world is running faster and faster. You could find a lot of examples videos everywhere, like this one, one of the most famous.

It's very surprising when you arrive in Oslo central Station and almost everyone isn't moving. Very funny and original to see; some guys tried to be creative with funny posture. Unfortunately, I didn't have my camera this time :-( But memories are in my head.
