If you live in Germany and would like to experience this on a smaller scale THIS WEEKEND, come to the CCC conference in Dresden, called Datenspuren, run by our local CCC Erfa-Kreis C3D2. It takes place from 18.09 - 20.09 in Zentralwerk Dresden. Entry is completely free of charge, with a donation being appreciated.
It is a beautiful and inclusive environment that highlights not only a lot local hackers, but also a lot of artists.
I was there last year and it was amazing! I totally recommend it.
