I'm sure this "edgy" computer convention thinks that the ball-pits in their lounge are a very cool idea, but the OCD in me thinks this is kind of a gross way to interact with your colleagues - so many germs in those pits!

People work at computers in the lounge area of the 25th Chaos Communication Congress (25C3) in Berlin on Dec. 27. The annual four-day conference, organized by the Chaos Computer Club (CCC), offers lectures and workshops and attracts an international audience of hackers, scientists, artists, and utopians. The 25C3s slogan is "Nothing to hide", the organiser's website said.
