Sorry for a pointless post, but this project gives me the CCC vibes. Y'all should attend one day, it's brilliant! In fact it's so rich in things and hacker exhibitions that you don't even have to go to the talks!
The 36th Chaos Communication Congress organized by the Chaos Computer Club, a traditional event run by the community for the community. Takes place from Dec 26 to Dec 30 in Leipzig (Germany). Tickets are available on this Thursday (November 21th) from 21:00:00 CET till, judging from past experience, 21:00:01 CET.
For clarification: CCC is used for Chaos Computer Club, who organizes the C3, the Chaos Communication Congress. Confusion guaranteed ;) for more info visit https://events.ccc.de/
